Paul is a 2011 science fiction comedy road film directed by Greg Mottola from a screenplay by Simon Pegg and Nick Frost. Starring Pegg and Frost, with the voice and motion capture of Seth Rogen as the title character, the film follows two science fiction geeks who come across an alien. Together, they help the alien escape from the Secret Service agents who are pursuing him so that he can return to his home planet. The film is a parody of other science-fiction films, especially those of Steven Spielberg, as well as of science fiction fandom in general.

It is a British-American venture produced by Working Title Films, StudioCanal, Big Talk Pictures and Relativity Media and distributed by Universal Pictures. Paul was released on 14 February 2011 in the United Kingdom and on 18 March 2011 in the United States to generally positive reviews from critics and grossed $98 million worldwide on a $40 million budget.
