The funniest character from Simon Pegg and Nick Frost's Paul isn't the little gray alien — it's Jeffrey Tambor's Adam Shadowchild. We interviewed Pegg and Frost and got the backstory on Tambor's arrogant science fiction author. [io9]
I really liked the movie, lots of great references (why don't more bars play the cantina music?) but I definitely don't think Adam Shadowchild was the best character.
...on a side note, why the hell they they reference a movie about a child with a nervous system disorder?
