Katherine Heigl is said to be really really ready to blow off TV and concentrate on making theatrical films only but still has a couple of reservations about making the big jump. A source close to the actress says: "She saw what can happen with someone like Jennifer Aniston, who was crazy successful on TV but can't seem to carry a film, and she tested the waters early."
The 29-year-old star of Grey's Anatomy actress - who has found success in romantic comedies 'Knocked Up' and '27 Dresses' - is said to be keen to be a movie star.
However, Katherine may be locked into her contract and will have to continue starring as the annoying Izzy Stevens on the small screen, even if it is a hit show. The source told Us Weekly magazine: "I don't think she'll be able to get out of it."
Katherine's next big film is the romantic comedy 'The Ugly Truth' with Gerard Butler.
