4. Thomas F. Wilson: Then
Modern pop culture can thank Wilson for delivery of the line “Hello McFly,” and the usage of “butthead” to refer to, well, anyone. As Biff Tannen, the bully who bullies the hell out of both Marty and his dad, George, Wilson delivered meathead jock lines with credible perfection. It was a matter of irony. Wilson had suffered from bullying as a kid. “A thin and sickly kid, I was pushed around and beaten up by bullies throughout my childhood,” Wilson told the Hollywood Reporter in 2015. “… I grew bigger than everybody and it stopped. I knew very well how they operate, and specifically the joy they take in scaring people.”
