While we've heard no confirmation that White Doug (aka Justin Bartha) will return for The Hangover Part III, Black Doug, played by comedian Mike Epps, will be playing a significant role as the former Las Vegas drug dealer once kidnapped by Ken Jeong in the original.

Plot details are being kept under wraps for the time being, but it has been suggested by returning members of the cast that this final installment of the trilogy will revolve around breaking Alan (Zach Galifianakis) out of a mental institution, with locations to include Los Angeles, Mexico, and a return to Las Vegas (which would make sense considering Black Doug's return).
