Zach Galifianakis surprises Atlanta audience

Zach Galifianakis is in Atlanta filming "Keeping Up With the Joneses," also starring Jon Hamm. (Here's a photo from the set!)

(UPDATE: Want to join em? The movie needs extras).

Jon has been spotted visiting Buckhead Atlanta and Zach's putting his time here to good use, stopping by Laughing Skull Lounge the other night to work out some new material.

We got a few photos from a source lucky enough to have chanced upon Zach's surprise set! These photos were provided to the AJC and are used with permission.
