Happy Days' Henry Winkler Almost Landed John Travolta's Role In Grease

But for one brief moment in Hollywood history, actor Henry Winkler could have played both heartbreakers.

So, it’s not hard to imagine The Fonz playing the role of head T-bird too.

But as history would have it, that summer lovin' wasn’t Winkler’s to enjoy.

He quipped, “I only realized afterward … it has already happened.

I’m already typecast.

I should’ve just shut up and had a really good time making that movie.

Now I go home, I say no, I have a Diet Coke.

John Travolta goes home … and buys a plane.”
