To coincide with the announcement that FX's television adaptation of Y: The Last Man  -- simply titled Y -- has officially been ordered to series, actor Barry Keoghan has posted to Twitter the first official image from the upcoming show.Keoghan will star in Y as protagonist Yorick Brown, the sole human survivor of a plague that kills every mammal with a Y chromosome (i.e. every male.)RELATED: Why FX's Y: The Last Man Adaptation Is Called Simply 'Y'The photo shared by Keoghan features a hooded figure, who we can assume is Yorick, walking down a street littered with corpses. Additionally, he appears to be carrying a kennel, which presumably houses Ampersand, Yorick's Capuchin monkey companion and fellow plague survivor.

Based on the DC/Vertigo comic book series Y: The Last Man by Brian K. Vaughan, Y takes place in a "post-apocalyptic world in which a cataclysmic event has decimated every male mammal save for one lone human. The new world order of women will explore gender, race, class and survival."
