The Hangover Part III has been filling out its cast for the third installment with Heather Graham, Sasha Barrese, Mike Epps, and Ken Jeong all set to return alongside stars Bradley Cooper, Ed Helms, and Zach Galifianakis.  Today, Variety reports that an actor who wasn't in the first movie will be joining the cast.  John Goodman is in talks to play a bit part as a bad guy in the upcoming sequel.  Variety says the role is "an antagonist in the vein of the character Paul Giamatti played in Hangover II."  Variety's article is also a bit confusing when it comes to mentioning big name actors like Robert Downey Jr. and Sean Penn.  The article could be read as those actors being on the wish list for Goodman's role, or that they're on director Todd Phillips' wish list for a role that hasn't been revealed.

Filming on the sequel is due to begin in September.  The Hangover Part III is due out May 24, 2013.
