Simon Pegg and Nick Frost star as two nerdy English men travelling to UFO hotspots around the US in this enjoyable comedy. They come across a sarcastic alien called Paul (voiced by Seth Rogen) and take him on their journey. Along the way, they also pick up a mad religious woman (Kristin Wiig), a granny (Robert DiNiro's wife from Meet the..) and a CIA agent (Jason Bateman). Not for children under 10, though, as there is a fair bit of swearing by the alien!
