Jim Sturgess chats about the crazy sci-fi of 'Upside Down'

Jim Sturgess follows his starring role in "Cloud Atlas" with another visionary film. "Upside Down," written and directed by Juan Solanas, is centered on two planets that are planted one on top of the other, with equal and opposite gravity. The rich live "up top" and the poor can be found "down below." The worlds above and below you appear upside down.

The film, opening Friday, follows a cross-planetary romance between Sturgess' Adam and Kirsten Dunst's Eden. We spoke with the 31-year-old British actor about it.
