Paul is a silly scifi movie that has been on my cable a lot lately. It has grown on me, it's cute.
It is a Simon Pegg effort. Two Brits are driving around the USA in an RV exploring the UFO scene. They meet an alien, and zaniness ensues. I guess it is a kind of chase scene movie and a buddy movie. I enjoyed at the end as they resolve each character, in particular "The Big Guy".
