All things considered, we don't think Marilyn Monroe had too many regrets when it came to her iconic career. She was the biggest female star of the Golden Age of Hollywood, and was never short of work. If she could have changed one thing about it, though, she might have accepted the part of Holly Golightly in 'Breakfast at Tiffany's.' Truman Capote had her in mind when he wrote the part, and thought he had her secured for the role until her agent advised her not to play a character who could be construed as a prostitute.
Monroe ultimately turned the part down, and it went to Audrey Hepburn. The film was a huge success, and Hepburn was propelled into the acting stratosphere. Instead of working with Capote, Monroe worked with her husband Arthur Miller on 'The Misfits,' - a seemingly cursed production which brought about the end of her marriage. Just one year later, she was dead.
