Heder left Big Lake (working title) last week over "creative differences," according to his rep. Gethard, 29, will now play the part of an unemployed IT specialist who moves back in with his parents and younger brother.

Gethard joins Saturday Night Live alums Chris Parnell and Horatio Sanz in the series, which will be produced by Gary Sanchez Productions, the company owned by Will Ferrell, Adam McKay and Chris Henchy. His casting was first reported by The Comic's Comic blog.

Production on the 10-episode season starts next week in New York.
