The new sci-fi satire Paul, about a wisecracking alien who gets mixed up with two road-tripping comic book nerds, opens in the United States on March 18th. We had a chance to chat with the stars of this unique comedy, including Simon Pegg (Star Trek), Nick Frost (Pirate Radio), Jason Bateman (Teen Wolf Too), Kristen Wiig (Whip It!), Bill Hader (Superbad), Joe Lo Truglio (Wet Hot American Summer) and Blythe Danner (Meet the Parents), as well as director Greg Mottola(Adventureland) in New York last week. We asked them about their favorite science fiction movies, the challenges of mixing comedy with CGI effects, Star Trek vs. Star Wars, and more.
