As the WORLD turns @RealRonHoward came to my book event in Sydney Australia.

SO exciting for everyone !

he wrote in a post with a photo of the two guys.

Howard then reshared the post, noting that he was in Australia doing post-production on his next film.

“A great creative experience but thats for another post.

We connected backstage and I watched him give a great speech to a huge crowd.

What a blast!”

He embodied the 1950s Greaser, wearing a leather jacket and riding a motorcycle.

He has great wisdom.

He has great warmth.

He has great ability.

And I have loved him from the minute that I met him."

“I was on the set.

“He took me around my shoulder, walked me to the back of the soundstage.

He said, ‘You know, the writers are working as hard as they can.

I wouldn’t hit our script.’

I said, ‘Ron, I will never hit it again as long as I live.'”

Despite his early struggles, Winkler is still most associated with the Fonz.
