Y: The Last Man is an American post-apocalyptic drama television series developed by Eliza Clark based on the comic book series of the same name by Brian K. Vaughan and Pia Guerra. In the series, a mysterious cataclysmic event simultaneously kills every mammal with a Y chromosome—except for Yorick Brown and his monkey–and follows him as he traverses the new world.

The series began development at FX in October 2015, with a pilot ordered and filmed in 2018. A first season was greenlit in 2019 with Clark replacing original showrunners Michael Green and Aida Mashaka Croal. Filming began in 2020, with several casting changes, including the lead role of Yorick. It premiered on September 13, 2021, on FX on Hulu, and Star with Disney+ in other territories, and stars Diane Lane, Ashley Romans, Ben Schnetzer, Olivia Thirlby, and Amber Tamblyn. It received generally positive reviews from critics, but was canceled in October 2021, after one season. The series was removed from Hulu and Disney+ on May 26, 2023, making it unavailable to stream on any platform in the United States or anywhere else.

Premise Y: The Last Man takes place in a post-apocalyptic world where a mysterious cataclysmic event simultaneously killed every mammal with a Y chromosome but for one man – Yorick Brown (Ben Schnetzer) – and his male pet monkey Ampersand. The series follows Yorick as he traverses the new world, as its survivors struggle with their losses and attempt to restore world society—led by Yorick's mother, who is the new U.S. President, Jennifer Brown (Diane Lane).

Gender effects In the original comic book series, every animal with a Y chromosome instantaneously dies at the same time, including most mammals. (Birds, reptiles, amphibians, fish, and invertebrates are unaffected because they mostly use different sex chromosomes.) While transgender people did not feature heavily in the original comic, it was mentioned that trans men survived due to not having Y chromosomes.

The producers aimed to update and expand on the ramifications of this, to reflect changing societal attitudes in the West toward gender in the almost two decades since the comic began. The showrunners specified that trans women with Y chromosomes also died, as did women with androgen insensitivity who were unaware they possessed Y chromosomes. The showrunners also added a trans male character to the regular cast (Sam Jordan, played by Elliot Fletcher), who does not have a direct counterpart in the original comic, to expand on this world-building.

Speaking at the August 2021 TCA panel, showrunner Eliza Clark said, "Yorick's maleness is not what sets him apart in this world — it's his Y chromosome that sets him apart. Gender is diverse and chromosomes are not equal to gender. And so, in our world — in the world of the television show — every living mammal with a Y chromosome dies. Tragically, that includes many women; it includes non-binary people; it includes intersex people ... We are making a show that affirms that trans women are women, trans men are men, non-binary people are non-binary, and that is part of the richness of the world we get to play with."

Cast member Fletcher said that, "In this world post the event, gender is somewhat irrelevant. I think one of the hilarious things about this show is that post the event, Yorick can walk around without a mask on because he's assumed to be trans, rather than pre-the-event, people are assumed to be cisgender. And so, I just think it flips the traditional idea of gender completely on its head, and so I was very comfortable joining a project that knew that ahead of time and committed to it fully."

Societal effects Showrunner Eliza Clark explained that the writing team tried to analyze the logical ripple effects of what would happen if all people with Y chromosomes died instantaneously. She said she was surprised at how even by 2020, there is still a large gender disparity in many aspects of essential infrastructure, ranging from the electrical power grid to something as basic as trucking to keep supply lines functional: "Basically what I learned is that our entire economy runs on trucks. So, if you're living in a city, you know when you go to a grocery store that grocery store needs two deliveries a day to be stocked for the number of people who are shopping [at] it, and they don't have storage. I think 5% of truck drivers are women."

Clark went on to say, that while all people with Y chromosomes are suddenly killed off, essentially removing the gender binary divide among the survivors, the resulting society that develops over the course of the series is not egalitarian. Other social divisions remain based on race, sexual orientation, politics, or wealth.

Governmental effects

In the United States, Republican president Ted Campbell dies along with his vice president, most of both houses of Congress, and six out of nine Supreme Court Justices (including men as well as women who died in accidents resulting from the event). The presidential line of succession is killed wholesale, losing the Speaker of the House, President pro tempore of the Senate, and (seemingly) all Cabinet officials. The surviving congresswomen hastily elevate the Chair of the House Intelligence Committee (Jennifer Brown, a Democrat) as Speaker, and in turn (within one hour) swear the new Speaker in as President.

President Campbell's politically active daughter Kimberly Campbell Cunningham begins rallying the surviving Republican congresswomen, urging that they were the lawfully elected party in power before the die-off, while Brown's new Executive branch was not elected but came into power through line of succession. There was also a higher ratio of female Democratic members than Republicans, at least temporarily tipping the balance in the surviving government.

Only two women were Cabinet heads – but Secretary of Education Abbott was born in Antigua and thus not eligible. The only eligible Cabinet head was Regina Oliver, who was visiting Israel at the time of the event and presumed dead. Later, however, it is discovered that Oliver survived: she was injured in a building collapse and left in a coma for several weeks, but recovers. Oliver is described even by moderate Republicans as a far-right radical who President Campbell only appointed to a minor Cabinet position as a concession to far-right swing voters. Even Kimberly Campbell's surviving Republican caucus considers Oliver a fringe lunatic, leaving them conflicted about pushing for her to replace Brown as president.

The effect of the die-off on other countries is not discussed in detail in the first season, in part because the world has been thrown into such chaos that even Jennifer Brown's fragile emergency administration still doesn't know. Other countries with few or no women in leadership positions fared much worse than the United States, which was itself crippled. In the third episode, it is briefly mentioned that the Russian government tried to spread propaganda that their male leadership had survived in isolation, but when rioters stormed the Kremlin and exposed this to be a lie, the Russian government collapsed.

Production Development

In October 2015, it was reported that FX had begun development on a television series adaptation of Brian K. Vaughan and Pia Guerra's comic book series Y: The Last Man. Vaughan was set to produce alongside Nina Jacobson and Brad Simpson. Production companies involved with the series were expected to include Color Force and FX Productions.

In November 2016, it was announced that Michael Green would serve as showrunner for the potential series in addition to writing a pilot script with Vaughan. In January 2017, it was reported that FX was expecting to receive the script in the next few months. In May 2017, it was clarified that Green had solely written the script and that Vaughan had read and liked it. In July 2017, it was confirmed that FX had received a draft of the script from Green, that they had liked it, and that discussions over the potential series were ongoing. In January 2018, FX CEO John Landgraf commented on the series' status during the annual Television Critics Association winter press tour saying, "[We feel] pretty optimistic, not quite at a final decision point. But we got a script I really like, a draft we really like recently." Landgraf went on to comment that Green was now available for the series following his departure from American Gods.

In April 2018, it was announced that FX had given the production a pilot order. Green was expected to co-showrun the series with Aida Mashaka Croal, both of whom were also set to executive produce alongside Melina Matsoukas, Jacobson, Simpson, and Vaughan. Matsoukas was also slated to direct the pilot episode. In February 2019, it was announced at the Television Critics Association's annual winter press tour that the production had been given a series order for a first season, expected to premiere in 2020.

In April 2019, Green and Croal exited the series, with creative differences cited. In June 2019, it was announced that Eliza Clark would be replacing Croal and Green as the showrunner. In February 2020, it was concluded that Clark, Nina Jacobson and Brad Simpson of Color Force, and Vaughan would executive produce. Matsoukas also serves as executive producer, as does Mari Jo Winkler-Ioffreda. Nellie Reed serves as producer. In May 2020, it was announced that the show's title had been changed from simply Y to Y: The Last Man. In June 2020, it was announced that the series would premiere FX on Hulu instead of FX's linear cable network. In October 2020, it was announced that along with serving as showrunner, Eliza Clark would also be writing the first two episodes, with Louise Friedberg directing those episodes. FX also announced that the entire first season would be directed by women. The series premiered with its first three episodes on September 13, 2021, with subsequent episodes released weekly.
