Simon Pegg and Nick Frost--the duo from Shaun of the Dead, Hot Fuzz, and Spaced--play a couple of road-tripping dweebs who pick up an alien who has the voice of Seth Rogen. Does this genuinely funny, surprisingly sweet comedy do for sci-fi what Shaun of the Dead did for zombie flicks or Hot Fuzz did for action epics? Ehh, not quite. But still: This'll be one of the better and funnier comedies you'll see this year. by Erik Henriksen
