Paul Giamatti has joined the cast of “The Hangover 2”, according to Deadline.

Giamatti, considered one of the big Oscar hopeful’s for next (due to his rousing performance in “Barney’s Version”), is jetting off to Thailand with cast members Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha for a few days to shoot his scenes.

It’s not known whether or not Giamatti’s role is a supporting role or merely a cameo, like the one Liam Neeson recently filmed for the film.
