The 44-year-old Hangover star is set to star in the pilot of an upcoming comedy for FX network that will be co-written by acclaimed actor/comedian Louis C.K.
Both Galifianakis and C.K. will be executive producers, alongside Blair Breard, Dave Becky, Andrea Pett-Joseph and Marc Gurvitz.
The pilot is the first project to be carried out under the deal between FX Productions and Louis C.K.'s production company Pig Newton, which was announced in early December.
