Part of Back to the Future featuring Michael J. Fox, Christopher Lloyd, Lea Thompson, and Crispin Glover.
Before he was Biff, Wilson was a kid who got beaten up regularly and knew exactly how bullies operate from the losing end. That experience gave Biff Tannen a nastiness that read as real. He'd been grinding stand-up at the Comedy Store in Los Angeles and doing summer stock when Back to the Future landed in 1985 as his film debut. He won a Saturn Award for Best Supporting Actor for his third version of the character in Part III, which means the bullied kid grew up to win awards for playing the bully.
Wilson has spent decades being stopped by people who want to ask him about hoverboards, and he responded by turning it into material. He carries pre-printed FAQ cards that answer every recurring question about the trilogy, and performs 'Biff's Question Song' in his stand-up routine. The act of repackaging fan obsession as comedy is probably the smartest thing he did. Away from Biff, he voices antagonists on SpongeBob SquarePants, paints portraits of classic toys (Disneyland added him to their California Featured Artists Series in 2006), and runs a YouTube channel.
His high school debate partner was David Brooks, who became a New York Times columnist. Wilson studied international politics at Arizona State before pivoting to the American Academy of Dramatic Arts, which is either a wasted degree or perfect training for playing someone who thinks he runs everything. He married Caroline Thomas on July 6, 1985, three days after Back to the Future hit theaters. The film is still running somewhere. So is the marriage.
