FX stressed that this is no April Fools gag. The network has made the entire fourth season of its Louis C.K. series Louie available for streaming via the FX Now app starting today through the premiere of Season 5 on April 9. Last season featured the episode “So Did The Fat Lady,” for which Louis C.K. earned a WGA Award and his second writing Emmy. Check out the long final scene — a memorable two-hander with Sarah Baker, who earned a Critics’ Choice nom for the role — to understand why. Season 4 of Louie also snagged the WGA trophy for Episodic Comedy and scored its second consecutive Emmy nom for Outstanding Comedy Series.
