In August 2009, FX picked up his new series, Louie, which C.K. stars in, writes, directs, and sometimes edits.[39] The show features his stand-up routines blended with segments which are based to some extent on his offstage experiences.[40] The show premiered on June 29, 2010. Each season of Louie contains 13 episodes.[41] The show addresses life as a divorced, aging father: "It's hard to start again after a marriage," he states in one of his early routines on the show. "It's hard to really, like, look at somebody and go, hey, maybe something nice will happen.... Or you'll meet the perfect person, who you love infinitely, and you even argue well, and you grow together, and you have children, and then you get old together, and then she's going to die. That's the best-case scenario."[26] In season three, episodes dealt with a date with an unstable bookshop clerk (played by Parker Posey),[42] a doomed attempt to replace a retiring David Letterman, an aborted visit to his C.K.'s father, and a dream-reality New Year's Eve episode in which C.K. ends up in China.[43] All of these made critic Matt Zoller Seitz's list of his favourite 25 comedy episodes of 2012.[44] According to Seitz, the episode "New Year's Eve" was "truly audacious", leaving the viewer "unmoored, uncertain what to trust, or how to see"[43] and "captur[ing] the sensation of dreaming better than any half-hour comedy episode [Seitz has] ever watched".[44] C.K. has been nominated three times for a Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series (2011, 2012, and 2013) for his work in Louie.[45] The show has been renewed for a fourth season.
