Biff Tannen's actor (Tom Wilson) went on to be a comic, musician, and even a painter. He had a few roles (mostly vocal roles) in films such as The Spongebob Squarepants Movie and the New Batman Adventures, if you can imagine that. But, obviously, none of these roles exceeded Biff Tannen, and he will live in infamy with the role of being the meathead bully.
