Simon Pegg. Nick Frost. And Now Seth Rogen
The movie, as you may recall, is a road trip comedy. Simon Pegg and Nick Frost will actually switch roles this time -- Pegg will play the doofus sidekick and Frost will play the hero. The two are sci-fi, comic-book fanatics of some sort who travel to Area 51 on their way to Comic Con only to discover that their wildest conspiracy theories are true when they meet an alien named Paul. Adventures ensue.
Today it was announced that several more cast members have been added to the production, and they're all solid. Seth Rogen, in fact, will be voicing the alien, Paul. In addition to him, Jason Bateman has been added, as well as two holdovers from Mottola's Adventureland, Kristen Wiig and Bill Hader, who are solid scene stealers (and should always remains that way).
Filming begins next month in New Mexico.
