Snowpiercer is an American post-apocalyptic dystopian thriller television series that premiered on TNT on May 17, 2020. It is based on both the 2013 film of the same name, directed by Bong Joon-ho and the 1982 French graphic novel Le Transperceneige by Jacques Lob, Benjamin Legrand and Jean-Marc Rochette, from which the film was adapted.

The series, a reboot of the film's continuity, follows the passengers of the Snowpiercer, a gigantic, perpetually moving train that circles the globe carrying the remnants of humanity seven years after the world becomes a frozen wasteland. The series questions class warfare, social injustice and the politics of survival. Jennifer Connelly and Daveed Diggs star alongside Mickey Sumner, Alison Wright, Iddo Goldberg, Susan Park, Katie McGuinness, Sam Otto, Sheila Vand, Mike O'Malley, Annalise Basso, Jaylin Fletcher, Lena Hall and Roberto Urbina. Steven Ogg, Rowan Blanchard and Sean Bean joined the main cast in the second season and both Chelsea Harris and Archie Panjabi joined the main cast in the third season.

While in development at TNT for over three years, the series faced numerous production issues and delays arising from creative differences between the series' producers and the network. The series remained in development hell until May 2019, when it was announced that the series would instead air on TNT's sister network TBS for a release in the second quarter of 2020 and that it had already been renewed for a second season. However, in September 2019, the decision to change networks was reversed.

Prior to studio shutdowns that occurred due to the outbreak of the COVID-19 pandemic in the United States, most of the second season's production was completed. The second season premiered on January 25, 2021. In January 2021, ahead of the second-season premiere, the series was renewed for a third season which premiered on January 24, 2022. In July 2021, ahead of the third-season premiere, the series was renewed for a fourth season. In June 2022, ahead of the fourth season premiere, it was announced that the fourth season would be its last, being intended to make it the final scripted original series to air on TNT before the production of original programming was ceased.

Premise

Snowpiercer is set in 2026, seven years after the world becomes a frozen wasteland, and follows the remnants of humanity who have taken shelter on a perpetually moving luxury train. Designed and built by the eccentric billionaire Mr. Wilford, the train consists of 1,001 carriages and circles the globe 2.7 times per year. The constant motion of the train provides energy and prevents the passengers from freezing as well. Since the catastrophe, the train's population has become rigidly separated by class, caught up in a revolutionary struggle against the strictly imposed social hierarchy and unbalanced allocation of limited resources. The show explores issues of class warfare, social injustice, and the politics of survival.

Cast and characters

Main

• Jennifer Connelly as Melanie Cavill: The powerful Head of Hospitality (the department responsible for smooth relations) and the Voice of the Train (responsible for making the PA system's daily announcements) aboard Snowpiercer. Though many of her peers are dismissive of the lower-class passengers, Melanie is curiously fascinated by them as she came from humble beginnings, explaining much of her sympathies. To the majority of the train, Melanie is believed to be Mr. Wilford's representative in relaying orders to the passengers and crew. It is later revealed Melanie has assumed his identity and is actually Snowpiercer's Head Engineer, working tirelessly to keep it functional. Melanie has been facing the crushing burden of directing Snowpiercer on its global journey, managing mounting resource and class issues, having her authority and decisions challenged and maintaining Wilford's iron order throughout the train to preserve the last of humanity. With few aware of her true identity, she is also desperate to maintain the myth of Wilford and keep her identity secret. Ultimately the secret is exposed, leading to a coup attempt by wealthy passengers from First Class, and a revolution by the Tail and Third Class sections with Melanie siding with Layton in the end. After the revolution, Melanie officially hands leadership of the train to Layton and resumes her duties as Head Engineer, but her plans to remain indefinitely in the engine room are threatened by the arrival of Mr. Wilford, and the surprise return of Melanie's believed-dead daughter Alexandra. In the second season, Melanie departs Snowpiercer to find a place that humanity can recolonize. In the second season finale, Layton and Alex discover that Melanie had sacrificed the last of her power to protect her data before seemingly walking into the Freeze to die, having ensured that humanity would have a future. In season three, Melanie appears as a hallucination to both Alex and Wilford. It's eventually discovered that she had actually survived by taking a track scaler from a nearby hanger and using the suspension drug to keep herself in hibernation. After being rescued, Melanie betrays Layton and seizes control of the Engine before agreeing to split the train with Melanie leading those who want to stay onboard Snowpiercer.
• Daveed Diggs as Andre Layton: A former detective, is a quiet thinker who spends his days tending to his cage of rats in the Tail, and a dangerous rebel who helps coordinate and lead a revolution against the oppressive First Class to improve the harsh living conditions in the tail end of the train. As he is the world's only surviving homicide detective, he is reluctantly deputized by Melanie as Snowpiercer's Train Detective, to help solve a series of murders; involving him and those he cares about in a struggle that could upend life on the train. Layton uses his new position as train detective to investigate the killings, while gathering intelligence and support for the revolution, and uses what he learns to start a revolution by the Tail and Third Class sections. After a bloody conflict, Layton's revolution succeeds and he is officially handed leadership of the train by Melanie. Originally planning to implement a new democratic government, his plans are threatened by the arrival of Mr. Wilford. While at times Layton and Melanie have been enemies, only by putting aside their differences and working together did they save Snowpiercer and overthrow the system. At the end of the second season, Layton creates his own pirate train out of the first ten cars of Snowpiercer in order to resist Wilford, taking with him several of his and Melanie's most trusted loyalists. At the end of the third season, Layton takes Big Alice and a number of people to a habitable valley in the Horn of Africa.
• Mickey Sumner as Bess Till: A thoughtful, empathetic, and savvy Brakeman who is part of the train's security force, she is a former Detroit PD first-year rookie officer who witnessed the department's self-destruction during the Freeze. She finds herself at the center of a series of murders that rocks the train's uneasy status quo. She is in a serious romantic relationship with Jinju, and later upgrades to Second Class to be with her. Tormented by witnessing the injustices of the class system, she ultimately breaks from the Brakemen and decides to support Layton's revolution, which cost her her relationship with Jinju. As a result, she becomes one of Layton's most trusted friends and allies. In season 2, Layton promotes her to Train Detective and Till struggles with her actions and her place in the world now. She joins Layton's pirate train at the end of the season. After the trains reconnect in season 3, Till resumes her role as Train Detective, investigating Pike's attempts to assassinate Layton and forming a romantic relationship with Miss Audrey. After Big Alice separated from Snowpiercer to embark on its journey to New Eden, Bess became the new Lead Brakemen aboard Snowpiercer.
• Alison Wright as Ruth Wardell: Melanie's deputy in Hospitality who helps look after First Class passengers, and oversees removal requests from the Tail, or delivering demands to them, activities she seems to feel are beneath her. Before the Freeze, she ran a bed and breakfast in Kendal, and was personally recruited for Snowpiercer by Mr. Wilford when he was a guest. Initially a friend to Melanie, she feels betrayed due to the recent revelations of the secrets Melanie was hiding from her and the rest of the train. After the revolution, Ruth is now Head of Hospitality, and is initially thrilled by Mr. Wilford's return, but begins to wonder whether Layton or Wilford is really the best thing for the train. When questioned by Layton, Ruth insists that her loyalty is to Snowpiercer and the passengers and Melanie believes that Ruth can be trusted as long as Layton remains honest with her. She subsequently acts as part of Layton's leadership council with Miss Audrey, Roche and Bennett Knox but he continues to be reluctant to trust her.

She represents Third Class before the rest of the train and is very vocal about the cruelty of the social differences aboard Snowpiercer, and pursues opportunities to demand more social conscience in the train, including supporting Layton's revolution. In season 2, she struggles with the return of Mr. Wilford and appears to be descending into alcoholism. She reveals to Layton that she was once an escort who served Wilford personally for years and has struggled to put her past behind her. In turn, Wilford is shown to have a genuine affection for her.

In season three, it's revealed that she gives birth to Liana Layton whom she allowed Wilford to experiment upon and give a cold immunity to. Zarah later encourages Layton and Josie to pursue a relationship, recognizing that she and Layton are better off as co-parents rather than a couple.
• Roberto Urbina as Javier "Javi" de la Torre: One of Snowpiercer's engineers, who is in the know about Melanie's impersonation of Mr. Wilford, but he often questions the morality of Melanie's decisions. He often helps with the driving of the train, and uses advanced algorithms and old hacked satellites remaining in Earth's orbit to predict the environment surrounding Snowpiercer at all times.

Initially believed to be the mysterious and reclusive Head Engineer of the train and is solely represented by Melanie, it is later revealed Melanie has assumed his identity and is the true Engineer; Wilford was believed to have died during the Freeze, after Melanie abandoned him to die at boarding, believing the remnants of humanity would not survive under his rule.

Production

Development

In November 2015, Marty Adelstein's Tomorrow Studios optioned the rights to develop a television series based on the 2013 film Snowpiercer. The film had been adapted from the 1982 French graphic novel Le Transperceneige by Jacques Lob, Benjamin Legrand, and Jean-Marc Rochette. The film's director Bong Joon-ho was attached as an executive producer alongside Adelstein and Josh Friedman, with the latter also set to write. A year later in November 2016, the project was ordered to pilot along with backup scripts by TNT with Friedman to serve as showrunner. In May 2017, it was announced that Scott Derrickson would direct the pilot written by Friedman. The pilot was picked up to series in January 2018. Later that month, Friedman was removed from the project by TNT due to "creative differences" with the network. Graeme Manson was appointed to replace Friedman as showrunner the following month. That June, Derrickson refused to return for reshoots on the pilot due to creative disputes with Manson, explaining via Twitter:

"The 72-page Snowpiercer TV pilot script by [Josh Friedman] is the best I've ever read. The feature-length pilot I made from that script may be my best work. The new showrunner has a radically different vision for the show. I am forgoing my option to direct the extreme reshoots."

Less than two weeks later, James Hawes joined the series in July as a co-executive producer and a director to oversee the reshoots for the pilot. According to Manson, nearly nothing of the original pilot's footage was used outside of one special-effect scene, and this reshooting was the primary cause for the year-long delay in the show's premiere. Later that month, Netflix picked up the international distribution rights to stream the series outside of the United States and China. In May 2019, it was announced that the series would air on TBS instead of TNT for a spring 2020 release, and that a second season had already been ordered by the network. That month, it was also announced that Huanxi Media Group had signed on to broadcast the first two seasons exclusively in China. Manson will return as showrunner for the second season. In September 2019, the decision to change networks was reversed, with the series once again set to air on TNT. On January 19, 2021, ahead of the second-season premiere, TNT renewed the series for a third season. On July 29, 2021, TNT renewed the series for a fourth season. On March 28, 2022, it was announced that Paul Zbyszewski is taking over as the showrunner and added as an executive producer for the fourth season. Following the formation of new parent company Warner Bros. Discovery in April 2022, original scripted content development was cut at TNT and TBS and in June, it was announced that the fourth season will be its final season.

Writing

The series is designed to be a reboot of the original 2013 film's continuity. The story takes place seven years after a climate catastrophe rendered the outside world uninhabitable, forcing the remnants of humanity to live confined inside of a massive train that constantly circles the globe. The series investigates class struggle, as the passengers of the train are segregated by wealth. The series star Daveed Diggs said that the show would "broaden exponentially" the world established by the film and the 1982 graphic novel. "That's one of the advantages of TV, you have time" Diggs said, "so the politics that are hinted at in the film are explored in much more depth and the mechanism of the train [is explored further] — just the little things that create a world, world specificity". At the 2017 Television Critics Association press tour, TNT and TBS president Kevin Reilly revealed that the Snowpiercer series would be akin to a "space ship show" due to its contained setting and that it would feature a mystery during the first season.

Casting

In May 2017, Daveed Diggs was cast as Andre Layton. The following month, Jennifer Connelly and Mickey Sumner landed the other lead roles of Melanie Cavill and Bess Till, respectively. Casting continued throughout the month of June with Annalise Basso as LJ Folger, Sasha Frolova as Pixi Aariak, Alison Wright as Ruth Wardell, Benjamin Haigh as Fergus McConnell, Roberto Urbina as Javi, and Katie McGuinness as Josie McConnell. That August, it was announced that Susan Park had joined the main cast as Jinju. In September, Lena Hall was cast as Sayori. The series order in January 2018 also revealed that Sheila Vand and Sam Otto had been cast in then-undisclosed roles as series regulars. Vand was reported to be playing Zarah, while Otto will play John "Oz" Osweiler. In August 2018, Iddo Goldberg and Jaylin Fletcher were added as series regulars in the roles of Bennett and Miles, respectively.

Casting for a number of recurring roles were also announced during the month of August, including Steven Ogg as Pike, Timothy V. Murphy as Commander Grey, Happy Anderson as Klimpt, Jonathan Lloyd Walker as Big John, and Aleks Paunovic as Bojan Boscovic. The following month in September, Shaun Toub and Kerry O'Malley were added to the recurring cast as Terence and Lilah Folger, respectively. In October 2018, Aaron Glenane was cast as The Last Australian alongside Fiona Vroom as Miss Gillies, both in recurring capacities. In March 2019, Rowan Blanchard was cast as Alexandra for a guest role with the option of becoming a series regular should the series be renewed for a second season. Blanchard's promotion to the main cast for the second season was confirmed with the series' renewal that May. In June 2019, Ogg was also promoted to series regular status for the second season. In October 2019, Chelsea Harris was announced in the recurring role of Sykes. Later that month, it was also announced that Sean Bean would be a series regular for the second season. In November, Tom Lipinski was added to the second season's recurring cast as Kevin. In December 2019, Sakina Jaffrey and Damian Young joined the second season's recurring cast as Mrs. and Mr. Headwood, respectively. On February 16, 2021, Archie Panjabi was cast as a new series regular for the third season. On March 4, 2021, Chelsea Harris was promoted to as a series regular for the third season. On March 28, 2022, Clark Gregg and Michael Aronov were cast in undisclosed capacities for the fourth season.

Filming

In January 2017, it was reported that filming for the series was scheduled to begin in mid-March of that year. By September 25, pilot director Scott Derrickson indicated that production for the series had officially commenced. Reshoots for the pilot, overseen by new director James Hawes, began on August 20, 2018 in Vancouver, British Columbia and concluded on January 24, 2019. Principal photography for the second season began on October 21, 2019 in Langley, British Columbia and was originally expected to end on March 20, 2020. In March 2020, production was shut down due to the COVID-19 pandemic. Lena Hall, who portrays Miss Audrey, confirmed in July 2020 that the last block of episodes for season 2—episodes 9 and 10—were being filmed. As of March 11, 2021, filming for the third season was in progress until at least July 23, 2021. Filming for the fourth season began on March 28, 2022 and concluded on August 6, 2022.

Design

Despite the series' roots as a graphic novel and film, production designer Barry Robison was told to give the train "its own identity". He conceived the massive locomotive on a "very, very long piece of paper," drawing the entire train in "about three days." His Vancouver design team, headed by Production Designer Stephen Geaghan, then set out to construct around 20 of the 1,001 cars of various sizes over four soundstages, heeding to TNT's orders to not make the train look "too sci-fi". Construction on each of the cars with contrasting classes took less than six weeks and was met with approval from series producer and film director Bong Joon-ho.

Release

Broadcast

The series debuted on TNT in the United States in the spring of 2020, while Netflix began to air the series globally outside of the United States and China. Huanxi Media Group is set to broadcast the first two seasons exclusively in China.

The series had originally been planned to premiere on May 31, 2020, yet was moved up to May 17, 2020 in early April. Brett Weitz, general manager for TNT, stated the earlier premiere was related to the COVID-19 pandemic in order to bring the series to viewers earlier. On October 8, 2020, at New York Comic Con, TNT announced the second season was set to premiere on January 25, 2021. The third season premiered on January 24, 2022.

Marketing

Cast members Connelly, Diggs, Wright, Sumner, Hall, and Ogg attended the 2019 San Diego Comic-Con International along with executive producers Manson, Adelstein, and Clements to promote the series and debut its first official trailer. As part of the promotion for the upcoming series, insect protein bars mimicking those from the film were made available at the event.

Reception

Critical response

Review aggregator Rotten Tomatoes collected 82 critic reviews, identified 63% of them as positive, and reported an average rating of 6.5/10 for the first season.
