pbr British comedy duo, Simon Pegg and Nick Frost, are back on the big screen in their new movie Paul.br ppbr The pair, who are best friends off-screen, wrote the sci-fi comedy together and drafted in Hollywood stars like Seth Rogen and the Alien queen herself Sigourney Weaver.br ppbr The film is about a pair of friends who come across a top-secret military base, meet a pretty cool alien called Paul and end up on a road trip with him, whilst trying to return the extra terrestrial to where he should be.br ppbr Simon Pegg says it is not a problem juggling a working relationship with their friendship: "It's where we're happiest, the chance to work and hang out with your best friend is a gift."br ppbr Paul follows on from Pegg and Frost's successes of both Shaun of the Dead and Hot Fuzz together.
