Films: '50/50,' 'Take This Waltz'

Funnyman Rogen gets sorta serious this fall, first with the poignant "cancer comedy" '50/50' and then 'Take This Waltz,' director Sarah Polley's second time behind the camera. The marriage drama finds Rogen married to Michelle Williams, who might just be falling for a handsome new neighbor, played by Luke Kirby.
