So what do you get when a couple of British nerds decide to go on a tour of UFO hotspots in the USA? They of course run into Paul.
"For the past 60 years, a wisecracking alien named Paul (Seth Rogen) has resided at a top-secret military base in America's UFO heartland. When Paul decides he has had enough of Earth, he escapes from the compound and hops on the first handy vehicle -- a rented RV manned by two British sci-fi nerds named Graeme (Simon Pegg) and Clive (Nick Frost). With federal agents and the father of an accidental kidnap victim on their tail, the two hatch a crazy plan to help Paul return to his spaceship."
"Imprisoned on the other side of the universe, the mighty Thor finds himself in a deadly gladiatorial contest that pits him against the Hulk, his former ally and fellow Avenger. Thor's quest for survival leads him in a race against time to prevent the all-powerful Hela from destroying his home world and the Asgardian civilization."
