Regrets, Henry Winkler has a few.
The 77-year-old actor has revealed he once turned down the role of Danny Zuko in the iconic film Grease – and says he was a "damn fool" for doing so.
Speaking to CNN's Chris Wallace, Winkler said he passed on the Grease role over fears of being typecast after playing Arthur "The Fonz" Fonzarelli on TV series Happy Days.
"I am a damn fool. I only realised years afterwards," he said.
"I thought, I've played the Fonz, I don't want to do it again."
