Paul

Paul (2011) is a British-American sci-fi comedy road film starring Simon Pegg and Nick Frost as two British comic-book geeks, Graeme and Clive, who are on a pilgrimage to America’s UFO heartland. While traveling across the U.S., they accidentally encounter a sarcastic, beer-drinking, and pot-smoking alien named Paul (voiced by Seth Rogen) who has escaped from a top-secret military base.
