"Scott in the comics almost reminds me of Homer Simpson; you get to see what's going on in his head, and there's not much going on," says Hollywood indie poster-boy Michael Cera when asked about his role as the title character in the adrenaline-soaked action comedy "Scott Pilgrim Vs. the World."

"There's always something very comfortable about playing an idiot," he adds. "You don't have to try to sound smart."

You know how half the Japanese blockbuster movies these days are based on some famous manga? Well "Scott Pilgrim" is based on a series of comic books too — but these ones were written and set in Canada, and soaked to the core in Japanese anime and video-game references. It's one of the most outlandish movies to come out of Hollywood in a while.
