At this point, Seth Rogen is a bona fide voice actor: he's been the pipes behind animated characters in Shrek the Third, The Spiderwick Chronicles, Horton Hears a Who, Kung Fu Panda, Monsters vs. Aliens, and the upcoming Simon Pegg/Nick Frost comedy Paul.  Now  DreamWorks Animation has signed Rogen to voice the lead ghost in Boo U.  According to Heat Vision, "the comic story centers on a ghost who must return to ghost school to learn how to be a better spook."  Tony Leondis (Igor) is on board as director.

Rogen will next be seen in live-action form in the Michel Gondry's 3D The Green Hornet (January 14, 2011).  His gruff voice can soon be heard again in the aforementioned Paul (March 18, 2011) and Kung Fu Panda 2 (May 26, 2011).
