Ricky Gervais is best known in the States as the creator of the UK version of The Office, though he also produces and sometimes writes for the US version. Now, he's also working on a comedy movie and the cast is looking bananas. From his website:

CASTING UPDATE....
Latest cast additions just confirmed - John Hodgman, Tina Fey, Christopher Guest, Jeffrey Tambor join Louis CK, Rob Lowe, Jonah Hill, Jennifer Garner.
Oh and me, Ricky Gervais, obviously. Not a bad cast for a comedy.

And even more recently there's an update that says even Jason Bateman may be joining the cast. The premise of the movie seems like it could certainly be amusing: "It's a comedy set in a world where no one has ever had the ability to lie. Until now."

I'll be keeping my eyes peeled for more info on this one.
