Actor Charlie Hunnam was left "heartbroken" after he was forced to quit the Fifty Shades Of Grey movie. The Sons of Anarchy star won the coveted role of Christian Grey last summer (13), but he exited the project months later, and now admits the decision was a difficult one. He tells Life & Style magazine, "I felt like I had an interesting take on that character and felt like I could have done a good job of playing Christian Grey, otherwise I wouldn't have taken it on in the first place. "When you put the time into something like that and a character comes alive in your mind, it's heartbreaking not to be able to play him... It was definitely kind of heartbreaking having to say goodbye to that character and not bring it to life." Following Hunnam's departure, Northern Irish actor Jamie Dornan was cast opposite Dakota Johnson, who will play Anastasia Steele in the movie, which is due out next year (15).
