The upcoming comedy This Side of the Truth is turning into quite a star-studded event, as Tina Fey, Jeffrey Tambor, Christopher Guest, and John "I'm a PC" Hodgman.

That's in addition to the already-in-place Ricky Gervais, Jennifer Garner, Jonah Hill, Louis C.K., and Rob Lowe.

Gervais wrote the script, which is about a man who discovers lying in a world that only ever tells the truth.
