Angelina Jolie reportedly insisted that her Wanted character must die at the film’s climax. According to MTV, the actress purposely changed the ending of the movie from the comic book on which it was based. “In the original, she doesn’t kill herself,” said Jolie. “I actually changed the ending. I said, ‘If she was to find out she had killed people unjustly and was a part of something that wasn’t fair, then she should take her own life’.” It is speculated that the star set the plot up that way so that she wouldn’t have to come on board for a sequel.
