Paul is a 2011 comic science fiction road film[4] 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.

Best friends Graeme Willy and Clive Gollings are British comic book and sci-fi enthusiasts who travel to the United States to attend the annual San Diego Comic-Con. Clive is trying to write his own sci-fi book, and Graeme is illustrating Clive’s book. In addition to going to the convention, they embark on a road trip through the Southwestern U.S. to visit UFO sites on a remote desert highway at night.

After a brush with homophobic rednecks at a diner, they watch a car driving erratically and crashing. Stopping to offer assistance to the driver, he is revealed to be Paul, an alien. Graeme agrees to give him a ride, despite Clive fainting and wetting his pants upon seeing him.

Later, Special Agent Zoil of the Secret Service arrives at the car-crash site, informing his unseen female superior, known as “the Big Guy,” that he is closing in on Paul. She sends rookies Haggard and O’Reilly to assist. Clive remains paranoid over Paul’s intentions, considering his appearance as evidence of a conspiracy. Then Paul explains the government fed his image to the public to keep them from panicking if anyone encounters his race.

Graeme, Clive, and Paul later camp at an RV park run by Christian fundamentalists, one-eyed Ruth Buggs and her father Moses. The next day, when Ruth sees Paul, she faints, so they take her with them. During an argument, Paul convinces Ruth to question her beliefs and uses his healing power to cure her blind eye.

Stopping at a bar, Ruth calls her father, but Zoil intercepts the call. She is accosted by the rednecks and a bar fight ensues. They escape when Paul terrifies them into fainting. Later, at another RV park, Ruth is questioned by Agent Zoil, but plays dumb and escapes. Meanwhile, Haggard and O’Reilly have figured out about Paul. They confront Zoil, who orders them to return to base, but they go behind his back and try to catch the alien on their own.
