Giallo (Italian pronunciation: [ˈdʒallo], plural gialli) is a 20th-century Italian genre of literature and film. In Italy, the term simply denotes thrillers, typically of the crime fiction and mystery subgenres, regardless of the country of origin. In English-speaking countries, however, the term "giallo" is used to refer to a particular style of Italian-produced murder mystery film which often includes elements of horror fiction and eroticism (similar to the French fantastique genre). The genre began in the late 1960s, peaked in popularity during the 1970s, and subsequently declined over the next few decades (though some examples continue to be produced up to the present day). It is considered to be a predecessor to, and significant influence on, the later American Slasher film genre.
The word "giallo" is Italian for "yellow." Its use as a label denoting the thriller genre derives from its association with a series of cheap paperback mystery novels, popular in post-fascist Italy, which were adorned with yellow covers.
The term giallo derives from a series of crime-mystery pulp novels entitled Il Giallo Mondadori ('Mondadori Yellow [books]'), published by Mondadori from 1929 on, and taking its name from the trademark yellow cover background. The series consisted almost exclusively of Italian translations of mystery novels by British and American writers, such as Agatha Christie, Ellery Queen, Edgar Wallace, Ed McBain, Rex Stout, and Raymond Chandler.
Published as cheap paperbacks, the success of the "giallo" novels soon began attracting the attention of other publishing houses, who began releasing their own versions, mimicking the yellow covers. The popularity of these series eventually established the word giallo as a synonym for a mystery novel, and in common and media language for a mysterious or unsolved affair
For Italian audiences, giallo has come to refer to any kind of thriller, regardless of its origin. Thus, American, British or other thrillers such as Psycho, Vertigo or Peeping Tom are considered gialli. For English-speaking audiences, however, the term has come to refer only to a very specific type of Italian-produced thriller which Italian audiences have historically referred to as "thrilling all'italiana" or "spaghetti thrillers."
The term giallo first referred to similarly themed crime and mystery pulp novels with yellow covers which became popular in post-fascist Italy. The film subgenre that emerged from these novels in the 1960s began as literal adaptations of the books, but soon began taking advantage of modern cinematic techniques to create a unique genre which veered into horror and psychological thrillers. Many of the typical characteristics of these films would subsequently be incorporated into the later American slasher genre.
There is some critical disagreement on exactly what elements comprise a giallo film. Critic Gary Neednam, considering the problem, writes:
"By its very nature the giallo challenges our assumptions about how non-Hollywood films should be classified, going beyond the sort of Anglo-American taxonomic imaginary that "fixes" genre both in film criticism and the film industry in order to designate something specific. ...however, despite the giallo's resistance to clear definition there are nevertheless identifiable thematic and stylistic tropes."
These distinct "thematic and stylistic tropes" constitute a loose definition of the genre which is broadly consistent, though various critics have proposed slightly differing characteristic details (which consequently creates some confusion over specifically which films can be considered gialli).
Although often based around crime and detective work, gialli should not be confused with the other popular Italian crime genre of the 1970s, the poliziotteschi, which includes more action-oriented films centering on violent law enforcement officers (largely influenced by Dirty Harry, The Godfather, and The French Connection). Directors and stars often moved between both genres, and some films could be considered under either banner, such as Massimo Dallamano's 1974 film La polizia chiede aiuto (What Have They Done to Your Daughters?). Nevertheless, most critics agree that the giallo represents a separate and distinct category with unique features.
Giallo films are generally characterized as gruesome murder-mystery thrillers that combine the suspense elements of detective fiction with scenes of shocking horror, featuring excessive bloodletting, stylish camerawork, and often jarring musical arrangements. The archetypal giallo plot involves a mysterious, black-gloved psychopathic killer who stalks and butchers a series of beautiful women. While most gialli involve a human killer, some also feature a supernatural element.
The typical giallo protagonist is an outsider of some type, often a traveler or tourist, and usually a young woman (gialli rarely feature law enforcement officers as chief protagonists, which would be more characteristic of the poliziotteschi genre). They are generally unconnected to the murders before they begin, and are drawn to help find the killer through their role as a witness to a crime. The mystery centers on the identity of the killer, who is often revealed in the climax to be another key character who conceals his or her identity with a disguise (usually some combination of hat, mask, sunglasses, gloves, and trench coat). Thus, the literary whodunit element of the giallo novels is retained, while being filtered through Italy's longstanding tradition of opera and staged grand guignol drama.
It is important to note, however, that while most gialli feature elements of this basic narrative structure, not all of them do. Some films (for example Mario Bava's 1970 Hatchet for the Honeymoon, which features the killer as the protagonist) may radically alter the traditional structure or abandon it altogether and still be considered gialli due to stylistic or thematic tropes, rather than narrative ones. In fact, one consistently observed element of the genre is an unusual lack of focus on coherent or logical narrative storytelling. While most have a nominal mystery structure, they may feature bizarre or nonsensical plot elements and a general disregard for realism in acting, dialogue, and character motivation. As writer Jon Abrams notes, "Individually, each [giallo] is like an improv exercise in murder, with each filmmaker having access to a handful of shared props and themes. Black gloves, sexual ambiguity, and psychoanalytic trauma may be at the heart of each film, but the genre itself is without consistent narrative form."
While a shadowy killer and mystery narrative are common to most gialli, the most consistent and notable shared trope in the giallo tradition is the focus on grisly death sequences. The murders are invariably violent and gory, featuring a variety of explicit and imaginative attacks. These scenes frequently evoke some degree of voyeurism, sometimes going so far as to present the murder from the first-person perspective of the killer, with the black-gloved hand holding a knife viewed from the killer's point of view. The murders often occur when the victim is most vulnerable (showering, taking a bath, or scantily clad); as such, giallo films often include liberal amounts of nudity and sex, almost all of it featuring beautiful young women (actresses associated with the genre include Edwige Fenech, Barbara Bach, Daria Nicolodi, Mimsy Farmer, Barbara Bouchet, Suzy Kendall, Ida Galli, and Anita Strindberg). Due to the titillating emphasis on explicit sex and violence, gialli are sometimes categorized as exploitation cinema. The association of female sexuality and brutal violence has led some commentators to accuse the genre of misogyny.
Gialli are noted for psychological themes of madness, alienation, sexuality, and paranoia. The protagonist is usually a witness to a gruesome crime, but frequently finds their testimony subject to skepticism from authority figures, leading to a questioning of their own perception and authority. This ambiguity of memory and perception can escalate to delusion, hallucination, and delirious paranoia. Since gialli protagonists are typically female, this can lead to what writer Gary Needham calls, "...the giallo's inherent pathologising of femininity and fascination with "sick" women." The killer is likely to be mentally ill as well; giallo killers are almost always motivated by insanity caused by some past psychological trauma, often of a sexual nature (and sometimes depicted in flashbacks). The emphasis on madness and subjective perception has roots in the giallo novels (for example, Sergio Martino's Your Vice Is a Locked Room and Only I Have the Key was explicitly based on Edgar Allan Poe's short story story "The Black Cat", which deals with a psychologically unstable narrator) but also finds expression in the tools of cinema: The unsteady mental state of both victim and killer is often mirrored by the wildly exaggerated style and unfocused narrative common to many gialli.
Writer Mikel J. Koven posits that gialli reflect an ambivalence over the social upheaval modernity brought to Italian culture in the 1960s. He writes,
"The changes within Italian culture... can be seen throughout the giallo film as something to be discussed and debated -- issues pertaining to identity, sexuality, increasing levels of violence, women's control over their own lives and bodies, history, the state -- all abstract ideas, which are all portrayed situationally as human stories in the giallo film.
Gialli have been noted for their strong cinematic technique, with critics praising their editing, production design, music, and visual style even in the marked absence of other facets usually associated with critical admiration (as gialli frequently lack characterization, believable dialogue, realistic performances, and logical coherence in the narrative). Writer Alexia Kannas argues of 1968's La morte ha fatto l’uovo (Death Laid an Egg) that "While the film has garnered a reputation for its supreme narrative difficulty (just as many art films have), its aesthetic brilliance is irrefutable," while critic Leon Hunt writes that frequent gialli director Dario Argento's work "vacillate[s] between strategies of art cinema and exploitation."
Gialli are frequently associated with strong technical cinematography and stylish visuals. Critic Maitland McDonagh describes the visuals of Profondo rosso (Deep Red) as, "vivid colors and bizarre camera angles, dizzying pans and flamboyant tracking shots, disorienting framing and composition, fetishistic close-ups of quivering eyes and weird objects (knives, dolls, marbles, braided scraps of wool)..." In addition to the iconic images of shadowy black-gloved killers and gruesome violence, gialli also frequently employ strongly stylized and even occasionally surreal uses of color. Directors Dario Argento and Mario Bava are particularly known for their impressionistic imagery and use of lurid colors, though other giallo directors (notably Lucio Fulci) employed more sedate, realistic styles as well. Due to their typical 1970s milieu, some commentators have also noted their potential for visual camp, especially in terms of fashion and decor.
Music has been cited as a key to the genre's unique character; critic Maitland McDonagh describes Profondo rosso (Deep Red) as an "overwhelming visceral experience...equal parts visual...and aural."  Writer Anne Billson explains, "The Giallo Sound is typically an intoxicating mix of groovy lounge music, nerve-jangling discord, and the sort of soothing lyricism that belies the fact that it's actually accompanying, say, a slow motion decapitation," (she cites as an example Ennio Morricone's score for 1971's Four Flies on Grey Velvet). Composers of note include Morricone, Bruno Nicolai, and the Italian band Goblin (all three of whom are probably best known for their collaborations with director Dario Argento, though they worked with other directors as well). Other important composers known for their work on giallo films include Riz Ortolani (composer for La ragazza dal pigiama giallo [The Girl in the yellow Pajamas]) and Fabio Frizzi (Sette note in nero aka The Psychic).
Gialli often feature lurid or baroque titles, frequently employing animal references or the use of numbers. Examples of the former trend include Sette scialli di seta gialla (Crimes of the Black Cat), Non si sevizia un paperino (Don't Torture a Duckling), La morte negli occhi del gatto (Seven Deaths in the Cat's Eye) and La tarantola dal ventre nero (Black Belly of the Tarantula); while instances of the latter include Sette note in nero (Seven Notes in Black Stars) and Giornata nera per l'ariete (The Fifth Cord).
History and Development
The first giallo novel to be adapted for film was James M. Cain's The Postman Always Rings Twice, adapted in 1943 by Luchino Visconti as Ossessione. Though the film was technically the first of Mondadori's giallo series to be adapted, its neo-realist style was markedly different from the stylized, violent character which subsequent adaptations would acquire. Condemned by the fascist government, Obsessione was eventually hailed as a landmark of neo-realist cinema, but it did not provoke any further giallo adaptations for almost 20 years.
In addition to the literary giallo tradition, early gialli were also influenced by the German "krimi" films of the early 1960s. Produced by Danish/German studio Rialto Film, these black-and-white crime movies based on Edgar Wallace stories typically featured whodunit mystery plots with a masked killer, anticipating several key components of the giallo movement by several years. Despite their link to giallo author Wallace, though, they featured little of the excessive stylization and gore which would define Italian gialli.
The Swedish director Arne Mattsson has also been pointed to as a possible influence, in particular his 1958 film Mannequin in Red. Though the film shares stylistic and narrative similarities with later giallo films (particularly its use of color and its multiple murder plot), there is no direct evidence that subsequent Italian directors had seen it.
The first "true" giallo film is usually considered to be Mario Bava's The Girl Who Knew Too Much (1963). Its title alludes to Alfred Hitchcock's classic The Man Who Knew Too Much (1934, remade by Hitchcock in 1956), highlighting the early link between gialli and Anglo-American crime stories. Though shot in black and white and lacking the lurid violence and sexuality which would define later gialli, the film has been credited with establishing the essential structure of the genre: in it, a young American tourist in Rome witnesses a murder, finds her testimony dismissed by the authorities, and must attempt to uncover the killer's identity herself. Bava drew on the krimi tradition as well as the Hitchcockian style referenced in the title, and the film's structure served as a basic template for many of the gialli that would follow.
Bava followed The Girl Who Knew Too Much the next year with the stylish and influential Blood and Black Lace (1964). It introduced a number of elements that became emblematic of the genre: a masked stalker with a shiny weapon in his black-gloved hand who brutally murders a series of glamorous fashion models. Though the movie was not a financial success at the time, the tropes it introduced (particularly its black-gloved killer, provocative sexuality, and bold use of color) would become iconic of the genre."
Several similarly-themed crime/thriller movies followed in the next few years, including early efforts from directors Antonio Margheriti (Nude... si muore [Naked You Die] in 1968), Umberto Lenzi (Orgasmo in 1968, Paranoia [A Quiet Place to Kill] and Così dolce... così perversa [So Sweet... So Perverse] in 1969) and Lucio Fulci (Una sull'altra [One on Top of the Other] in 1969), all of whom would go on to become major creative forces in the burgeoning genre. But it was Dario Argento's first feature, in 1970, that turned the giallo into a major cultural phenomenon. That film, The Bird with the Crystal Plumage, was greatly influenced by Blood and Black Lace, and introduced a new level of stylish violence and suspense that helped redefine the genre. The film was a box office smash and was widely imitated. Its success provoked a frenzy of Italian films with stylish, violent, and sexually provocative murder plots, (Argento alone made three more in the next five years) essentially cementing the genre in the public consciousness. In 1996, director Michele Soavi wrote, "there's no doubt that it was Mario Bava who started the "spaghetti thrillers" [but] Argento gave them a great boost, a turning point, a new style...'new clothes'. Mario had grown old and Dario made it his own genre... this had repercussions on genre cinema, which, thanks to Dario, was given a new lease on life." The success of The Bird with the Crystal Plumage provoked a decade which saw multiple gialli produced every year. In English-language film circles, the term "giallo" gradually became synonymous with a heavy, theatrical and stylized visual element.
The giallo genre had its heyday from 1968 through 1978, with dozens of films released. The most prolific period, however, was the three-year timespan between 1971 and 1973, during which time 65 different gialli were produced (see filmography below). Directors like Bava, Argento, Fulci, Lenzi, and Margheriti continued to produce gialli throughout the 70s and beyond, and were soon joined by other notable directors including Sergio Martino, Paolo Cavara, Armando Crispino, Ruggero Deodato and Bava's son Lamberto Bava. The genre also spread to Spain by the early 70s, resulting in films like La residencia (The House That Screamed) (1969) and Los Ojos Azules de la Muneca Rota (Blue Eyes Of The Broken Doll) (1973) which had unmistakable giallo characteristics but feature Spanish casts and production talent. Though they preceded the first giallo by a few years, German krimi films continued to be made contemporaneously with early gialli, and were also influenced by their success. As the popularity of krimis declined in Germany, Rialto Film began increasingly pairing with Italian production companies and filmmakers (such as composer Ennio Morricone and director/cinematographer Joe D'Amato, who worked on later krimi films following their successes in Italy). The overlaps between the two movements is strong enough that one of Rialto's final krimi films, Cosa avete fatto a Solange? (What Have You Done to Solange?), features an Italian director and crew and has been called a giallo in its own right.
Gialli continued to be produced throughout the 1970s and 1980s, but gradually their popularity diminished and film budgets and production values began shrinking. Director Pupi Avati satirized the genre in 1977 with a slapstick giallo titled Tutti defunti... tranne i morti.
Though the giallo cycle waned in the 1990s and saw few entries in the 2000s, they continue to be produced, notably by Argento (who in 2009 released a film actually titled Giallo, somewhat in homage to his long career in the genre) and co-directors Hélène Cattet & Bruno Forzani, whose Amer (which uses music from older giallis, including tracks by Morricone and Bruno Nicolai) received a positive critical reception upon its release in 2009. To a large degree, the genre's influence lives on in the slasher films which became enormously popular during the 1980s and drew heavily on tropes developed by earlier gialli.
The giallo cycle has had a lasting effect on horror films and murder mysteries made outside of Italy since the late 1960s. This cinematic style and unflinching content is also at the root of the gory slasher and splatter films that became widely popular in the early 1980s. In particular, two violent shockers from Mario Bava, Hatchet for the Honeymoon (1970) and Twitch of the Death Nerve (1971) were especially influential.
Early examples of the giallo effect can be seen in the British film Berserk! (1967) and the American mystery-thrillers No Way to Treat a Lady (1968), Klute (1971), Pretty Maids All in a Row (1971, based on an Italian novel), Alfred Hitchcock's Frenzy (1972), Vincent Price's Madhouse (1974) and Eyes of Laura Mars (1978). Berberian Sound Studio (2012) offers an affectionate tribute to the genre.
Director Eli Roth has called the giallo "one of my favorite, favorite subgenres of film," and specifically cited Sergio Martino's Torso (I corpi presentano tracce di violenza carnale) (along with the Spanish horror film Who Can Kill a Child?) as influential on his 2005 film Hostel, writing, "...these seventies Italian giallos start off with a group of students that are in Rome, lots of scenes in piazzas with telephoto lenses, and you get the feeling they're being watched. There's this real ominous creepy feeling. The girls are always going on some trip somewhere and they're all very smart. They all make decisions the audience would make."
