Ben Affleck turned to Matt Damon for help as he struggled with the final cut of his directorial debut, GONE BABY GONE. The Good Will Hunting star, 35, admits he had been "agonising" over some of the scenes in his new movie, which stars his brother Casey as a private detective searching for a missing four-year-old girl. He tells U.S. talkshow host Larry King, "Matt was very helpful, actually. I kind of waited to show it to him until I was in the middle of cutting the movie... and he was very helpful. "I had a few decisions that I was agonising over and I showed it to him. And he had some really good ideas, not surprisingly, a very smart guy, and he has been very supportive of the movie."
