Before Bradley Cooper, Ed Helms, and Zach Galifianakis were cast as the three-fourths of a wolf pack in The Hangover, director Todd Phillips reportedly considered dozens of other actors for the roles. According to Phillips, before Cooper was cast as the immature high school teacher Phil in the film, Paul Rudd was offered the part, but he ultimately turned it down. Bonus: Jack Black also turned down the role of Alan, which eventually went to Zach Galifianakis.
