Infernal Affairs is a 2002 Hong Kong action thriller film[2] co-directed by Andrew Lau and Alan Mak. Jointly written by Mak and Felix Chong, it stars Andy Lau, Tony Leung, Anthony Wong, Eric Tsang, Sammi Cheng and Kelly Chen. The film follows a police officer who infiltrates a Triad, and another officer secretly working for the same gang. It is the first in the Infernal Affairs series and is followed by Infernal Affairs II and Infernal Affairs III.

The film was selected as the Hong Kong entry for the Best Foreign Language Film at the 76th Academy Awards but was not nominated. Miramax Films acquired the United States distribution rights and gave it a limited US theatrical release in 2004. Martin Scorsese remade the film in 2006 as The Departed, which won the Academy Award for Best Picture as well as Best Adapted Screenplay. In 2017, an Indian remake of the film was also planned.[3]


Infernal Affairs focuses on a police officer named Chan Wing-yan (Tony Leung), who goes undercover into a triad, and a triad member Lau Kin-ming (Andy Lau), who infiltrates the Hong Kong Police Force. Each mole has been planted by the rival organisation to gain an advantage in intelligence over the other side. The more the moles become involved in their undercover lives, the more issues they have to cope with.

The prologue opens with the introduction of triad boss Hon Sam (Eric Tsang) ("Brother Sam"), who sends a number of young gangsters to the police academy as moles, among whom include a young Lau. Concurrently, a young Chan joins the police force but is seemingly expelled from the academy even though he manages to impress Superintendent Wong Chi-shing (Anthony Wong). In reality, Chan has become an undercover agent reporting only to Wong. Over the course of ten years, Chan experiences great stress from his undercover work while Lau quickly rises through the ranks in the police department. The film begins with a meeting between Chan and Lau in a hi-fi store without either of them knowing the other's identity.

Wong and his team interrupt a deal between Brother Sam and a Thai cocaine dealer after receiving a tip-off from Chan using Morse code. However, Lau alerts Brother Sam, giving him enough time to order his minions to dispose of the cocaine, eliminating solid evidence of the drug deal. After the incident, Wong and Sam are both aware that they each have a mole within their respective organisations, placing them in a race against time to root out the other mole. Later, Chan sees Sam conversing with Lau at a cinema but does not see Lau's face clearly; he ultimately fails to capture Lau. By this time, both Chan and Lau are struggling with their double identities – Chan starts losing faith in himself as a cop after being a gangster for ten years; Lau becomes more accustomed to the life of a police officer and he wants to erase his criminal background.

At their next meeting, Wong intends to pull Chan out of undercover work for fear of his safety. They are unaware that Lau has his subordinate, CIB Inspector "Big B", tracking him. Meanwhile, Brother Sam sends "Crazy" Keung and other henchmen to confront them after receiving intel from Lau. Inspector Big B informs Lau and sends an OCTB squad to save Wong. Chan flees from the building using a crane while Wong sacrifices himself to save him by distracting Sam's men. Wong is beaten and thrown off the roof by the gangsters. As the police close in, a shootout ensues in which several gangsters are killed. Keung drives Chan away from the scene, but later dies from a mortal gunshot wound. It is reported on the news that Keung himself was an undercover cop; Sam assumes that he was the mole and that Chan killed him to protect the triad.

Lau retrieves Wong's cell phone and contacts Chan, with both of them agreeing to foil a drug deal by Sam. The plan succeeds and many of Sam's men are arrested, while Lau betrays Sam and kills him. Everything seems to have returned to normal – Chan can revert to his true identity as a cop, while Lau has erased his criminal connections by eliminating Sam's triad. However, back at police headquarters, Chan discovers that Lau was the mole and leaves immediately. Lau, realising what has happened, erases Chan's file from the police database and makes a copy on his personal computer, intending to use the proof of Chan's identity as leverage, so that Chan would not reveal his real identity. Chan spends an evening with his therapist, Dr. Lee Sum-yee, with whom he has fallen in love. He sends to Lau a compact disc with a recording that Sam kept between himself and Lau; the disc is inadvertently intercepted by Lau's girlfriend, Mary.

Chan and Lau meet on the same rooftop where Wong was killed earlier. Chan disarms Lau and holds his Glock 17 to Lau's head; Lau states calmly that he "wants to be a good person" now, but Chan rejects Lau's plea to help conceal his criminal past. Big B arrives on the scene shortly and orders Chan to release Lau. Chan holds Lau as a hostage at gunpoint and backs into an elevator, but upon moving his head from behind Lau he is suddenly shot in the head by Big B. Big B then calls Lau his "brother", revealing to him that he was also a mole planted by Sam. Big B assures Lau that he has destroyed the tape which contained evidence of Lau's criminal past. As they take the lift down to the lobby, Lau shoots Big B.

The original ending climaxes with Lau identifying himself to the police as one of them. Lee discovers records revealing Chan as the undercover officer; Big B is blamed of being the mole within the force and the case is closed. Lau salutes Chan at his funeral, with Cheung and Lee present as well. A flashback reaffirms the point that Lau wished he had taken a different route in life. In mainland China, an alternate ending for the film was screened, in which Lau exits the elevator and is informed by Cheung that the police have found evidence that he was a mole. Lau hands them his badge and is arrested without protest. The sequel Infernal Affairs III uses the original ending instead of the alternate one.

Alternate ending[edit]

An alternate ending for the film was shot in order to comply with Article 25 (7) of the Chinese Film Administration Regulations specifying that films cannot propagate obscenity, gambling or violence, or abet to commit crimes.[4] In the original (Hong Kong) ending, Lau concealed his true identity as a criminal undercover and identified himself as a police officer to avoid legislative punishment. Therefore, the original ending version promotes criminal activity and injustice, and an alternate ending was filmed in order to access the market of mainland China. In the alternate ending, inspector Cheung discovered evidence of Lau’s criminal activity and immediately arrested Lau outside the elevator. This alternate ending was shown in mainland China and Malaysia.[5]


Postcolonial identity crisis in Hong Kong[edit]

In Infernal Affairs, the identity crisis suffered by both Chan and Lau as a mole is hinting at the schizophrenic struggle of Hong Kong residents, who faced both the colonization by the British and the recolonization by Mainland China. Specifically, under Deng Xiaoping’s "One Country, Two System policy", the duplicity, unsettling, and uncertain nature of the future of Hong Kong residents is tightly echoed in Chan and Lau’s character developments. Scholar Howard Y. F. Choy further claimed that “this postcolonial (re)turn is actually more a recolonization than a decolonization of the capitalist Cantonese city by the mainland Mandarin master.”[6]

Quotes from Buddha[edit]

Infernal Affairs opens with Buddhist classic Nirvana Sutra Verse Nineteen, stating that “The worst of the Eight Hells is called Continuous Hell. It has the meaning of Continuous Suffering. Thus the name.” The film also closes with another quote from Buddha, stating that “He who is in Continuous Hell never dies. Longevity is a big hardship in Continuous Hell.” In Buddhism, Continuous Hell is also termed The Avici, where one can never reincarnate nor be relieved from guilt and suffering. This concept of timeless, placeless, and endless suffering especially applies to the character Lau throughout the trilogy, who infinitely bears the burden of self-betrayal (serves as a mole), loss of family and friendship, and unsettledness.[7]


Box office[edit]

Upon its premiere in Hong Kong, Infernal Affairs grossed $160,356 during the opening day (January 16-19).[8] In total, the film grossed $7,035,649 during its run in Hong Kong theatres.[9] The film was then released across Asia, where it grossed a further $169,659 from theatre receipts.[10] In 2016, South Korean theaters re-released the film, which went on to gross $128,026 across three weeks.[11] The total lifetime gross of the film in Korea is $977,903.[12]

In total, worldwide, the film grossed $8,836,958 across release in both domestic markets and European theatres which displayed the film.

Critical response[edit]

On Rotten Tomatoes, Infernal Affairs has an approval rating of 94 percent based on reviews from 60 critics. The consensus from the site reads as "A blistering thriller and an intelligent character study and a comic take-off on the conventions of thrillers."[13] On Metacritic the film has a score of 75 out of 100 based on reviews from 19 critics. It was ranked as the #62 Best Movie of 2004, #78 Most Discussed Movie of 2004, and the #95 Most Shared movie of 2004.[14]

Film critic Roger Ebert gave the film a three-out-of-four star rating and described Infernal Affairs as offering "rare emotional depth." In his words, "The movie pays off in a kind of emotional complexity rarely seen in crime movies. I cannot reveal what happens but will urge you to consider the thoughts of two men who finally confront their own real identities—in the person of the other character."[15] New York Times reviewer Elvis Mitchel was so enraptured with the film that he stated that "Infernal Affairs is so beautifully shot that the images occasionally distract you from the condensed policier plot."[16]


Infernal affairs played an integral role in Andrew Lau’s breakout films in entering the 21st century. Being the most critically acclaimed film of his to date, it was ranked No.30 in Empire’s Magazine “The 100 Best Films of World Cinema” in 2010.

Infernal affairs gained significant traction during its festival run as it was nominated for sixteen awards during the 22nd Hong Kong Film Awards while winning 7 of those categories. This included beating out Hero for the best film award.

Infernal Affairs would also win the best picture at the 40th Golden Horse Awards, the 8th Golden Bauhinia Awards, and the best foreign-language film at the 46th Blue Ribbon awards.

Eventually, Infernal affairs would spark the creation of two more films in creating a trilogy. Infernal Affairs II would get 11 nominations during the 23rd Hong Kong Film Awards, winning Best Original Film Song.[17] Within the same festival Run, Infernal Affairs III would win the Best film category during the 23rd Hong Kong Film Awards.[18]

The theme song, Infernal Affairs (無間道), was composed by Ronald Ng, lyrics provided by Albert Leung, and performed in Cantonese and Mandarin by Andy Lau and Tony Leung.

Although not included in the soundtrack, Tsai Chin's (蔡琴) song "Forgotten Times" (《被遺忘的時光》) features prominently in this film as a recurring element of its storyline, and also in its sequels.



In fact, Mak Zhaohui, the script writer of Infernal Affairs, has long wanted to write a story about police and gangsters, but the script of Infernal Affairs is different from the usual police and gangster films. He focuses more on human nature and the human heart.[19] In the process of Mak's creation, his good friend Zhuang Wenqiang also encouraged and supported him. The script, written by Mak and revised by Chong, took three years to complete.


Infernal Affairs could not find investors after the script was written, because all the studios thought that an undercover film wasn't novel enough to make money. The Zhuang Cheng that Liu Weiqiang still is holding the psychology that tries finally to atlanto Asia entertainment sent the script, what unexpected are Zhuang Cheng and Lin Jianyue of company boss feel this double undercover film has a bright future.[20] Then Lin decided to invest HK $20 million in the film, but to invite Andy Lau, Tony Leung Chiu-wai, Wong Chiu-sheng, Tsang Chih-wai, and others to star in the film, because these stars may be more appealing than the plot of the film, and the star effect can bring higher box office value.


With star power, visual allure, and an engaging script, Andrew Lau and Alan Mak’s Infernal Affairs /《無間道》(2002) did very well critically and financially, spawned two sequels and a television series, and attracted the attention of Hollywood.[21] In 2003, Brad Pitt's production company Plan B Entertainment acquired the rights for a Hollywood remake, named The Departed, which was directed by Martin Scorsese, and starred Leonardo DiCaprio, Matt Damon, Jack Nicholson, and Mark Wahlberg, set in Boston, Massachusetts, roughly based on the life of famed Boston mobster James "Whitey" Bulger. The Departed was released on 6 October 2006 and won the Academy Award for Best Picture. Andrew Lau, the co-director of Infernal Affairs, who was interviewed by Hong Kong newspaper Apple Daily, said: "Of course I think the version I made is better, but the Hollywood version is pretty good too. [Scorsese] made the Hollywood version more attuned to American culture." Andy Lau,[22] one of the main actors in Infernal Affairs, when asked how the movie compares to the original, said: "The Departed was too long and it felt as if Hollywood had combined all three Infernal Affairs movies together."[23] Lau pointed out that the remake featured some of the "golden quotes" of the original but did have much more swearing. He ultimately rated The Departed 8/10 and said that the Hollywood remake is worth a view, though according to Lau's spokeswoman Alice Tam, he felt that the combination of the two female characters into one in The Departed was not as good as the original storyline.[24]

Lau, Tsang, and Jacky Cheung parodied the cinema scene to promote the Hong Kong Film Awards. Lau and Tsang, in their respective characters, go through the scene where they meet to gather info on the undercover cop amongst Hon Sam's gang. Lau Kin-ming asks Hon "Why do we always meet in a cinema?", to which Hon answers "It's quiet. No one comes to movies". Cheung comes out from the shadows behind them and says "I don't know...quite a few people watch movies" and we see a slew of Hong Kong celebrities watching various clips of Hong Kong films on the screen. Originally Tony Leung was going to appear but scheduling conflicts led to the recasting.

The 2003 TVB spoof celebrating the Chinese New Year called Mo Ba To (吐氣羊眉賀新春之無霸道), the 2004 comedy film Love Is a Many Stupid Thing by Wong Jing, and the 2004 TVB television drama Shades of Truth were re-writings based on the plot of the film.

In Taiwan SHODA (劉裕銘) and a secondary school student Blanka (布蘭卡) cut and rearranged the original film and inserted new sound tracks to produce their videos Infernal Affairs CD pro2 and Infernal Affairs iPod on the web. The videos had many views and both producers removed their videos after receiving cease and desist letters from the Group Power Workshop Limited (群體工作室), the Taiwan distributor of the film.[25]

Media Asia released a limited edition of eight-DVD set of the Infernal Affairs trilogy in an Ultimate Collectible Boxset (無間道終極珍藏DVD系列(8DVD套裝)) on 20 December 2004. Features included an online game and two Chinese fictional novels of the film series by Lee Muk-Tung (李牧童), titled 無間道I+II小說 and 無間道III終極無間小說.

The hi-fi shop scene was later recreated with additions of excerpts of the film to encourage businesses to join the Quality Tourism Services Scheme in Hong Kong.[26]

In 2009, a Korean remake City of Damnation, which was directed by Kim Dong-won was released on 22 January 2009.[27] In 2009, a Telugu remake Homam, which directed and acted by JD Chakravarthy along with Jagapathi Babu was released and became a notable movie.[28][29] In 2012, Double Face (ダブルフェイス), a Japanese television remake starring Hidetoshi Nishijima was released by TBS and WOWOW.[30] The production aired in two parts: "Police Impersonation" on WOWOW and "Undercover" on TBS.

A TV series remake debuted in 2018 produced by Media Asia and former TVB producer Tommy Leung. The series, which is titled Infernal Affairs like the film, stars Gallen Lo, Damian Lau, Paul Chun, Lo Hoi-pang, Eric Tsang, Derek Kok, Dominic Lam, Toby Leung and Yuen Biao.[31] The TV series uses the same concept as the film, but with an entirely new story and characters, and the setting expanded beyond Hong Kong to include Thailand and Shezhen. It stretched through three seasons with each season consisting of 12 episodes.[32]

Hindi remake is going to be a joint development between Warner Bros. India and Mumbai – based banner Azure and is set for a remake for a two-picture deal[33]

The success of the film inspired many genres, including an open-world video game from United Front Games titled Sleeping Dogs (or True Crime: Hong Kong before canceled by Activision Blizzard in 2011),[34] with the protagonist of the story infiltrating the criminal underworld as an undercover police.

Influence and Artistry[edit]

The Influence of Infernal Affairs on Hong Kong Cinema[edit]

Infernal Affairs is the turning point of Hong Kong film aesthetics. Before Infernal Affairs, there were few serious and artistic works in Hong Kong films, but they basically had the following characteristics: 1.The relative roughness of the production was compensated for by the skill of the practitioners 2.Hong Kong films incorporate a lot of dramatic elements After the release of Infernal Affairs, Hong Kong films began to pay attention to the plot and picture.[35]

The Artistry of the Infernal Affairs title[edit]

"Insanity" refers to the Insanity Hell, and in the Buddhist view, those who enter the Insanity Hell are extremely sinful. Those who enter the Infinite Hell never have any hope of relief, and they have no other feeling out of suffering. Those who enter the Infinite Hell will forever be tortured in Hell as retribution for the wickedness of their previous lives. The title perfectly sums up the plot described in The Infernal Affairs. Two identities should not belong to their own people, as they live in a similar hell of the environment; the dream is afraid of others who expose their undercover identity. Both of them are trying to use their own hated identities to hide their real identity. Their position in tandem with their identity force them to be tortured all the time, which perfectly fits the Buddhist-influenced title.[36]
