#13: Can You Imagine a Different Bud and Kelly?
Christina Applegate and David Faustino weren’t the original choices for Kelly and Bud Bundy. In the unaired pilot, the roles were played by Tina Caspary and Hunter Carson. However, after the episode was shot, the producers felt the sibling dynamic wasn’t quite right and decided to recast.

Enter Applegate and Faustino, who went on to define the characters for over a decade. As for Caspary and Carson, they continued acting but never reached the same level of success in Hollywood.
