Heigl: 'Hathaway was scared of Knocked Up role'

Anne Hathaway turned down the lead role in romantic comedy 'Knocked Up' because she deemed the movie "too radical", according to the film's star Katherine Heigl.

The 'Grey's Anatomy' beauty landed the role of Alison Scott opposite Seth Rogen after Hathaway, who was the original choice of director Judd Apatow, refused to take the part.
