“Paul” is another alien movie that feels like ET just phoned it in from home. Simon Pegg and Nick Frost (Hot Fuzz) play Graeme and Clive, two British comic book geeks who decide to go on a tour of America’s famous alien tourist spots (think area 51). They come face to face with the real thing when they meet Paul (voiced by Seth Rogen), a little green alien who escaped from a government lab and now must trust Graeme and Clive with getting him to a safe spot for a space ship pick-up.
