2. Julia Roberts and Kiefer Sutherland
In Runaway Bride, Julia Roberts plays a serial heartbreaker who gets skittish and literally runs away from the altar. What she did with Kiefer Sutherland wasn’t as dramatic. She broke up with him 3 days before the ceremony. Kiefer Sutherland later said that he had nothing but praise for what Julia did because they were too young to realize then that they were mismatched.
