Ron Howard has been in the spotlight since he was six years old, having played Opie Taylor on the classic TV show "The Andy Griffith Show." Since then, he's acted in "Happy Days," directed countless films ("Apollo 13," "A Beautiful Mind," "Cocoon") and started a very successful production company. But while you might think you know everything about Howard, as it turns out, he still has a few surprises up his sleeve.
"Something I am not too proud of, so therefore not many people know too much about it, is when I was in high school, we had a rivalry -- I was at Burroughs High School, our crosstown rivals were Burbank High School -- and on the basketball team I started a bench-clearing brawl," Howard told us. "And it was one of those things where the guy I was guarding was somebody I played with a lot; he was a bit of a rival. I fouled him hard, he threw an elbow, I took a wild swing, nobody really hit anybody, and then suddenly the stands just went Woosh! And it was bad and a couple really did get hurt, so it wasn't all in fun. It was dangerous."
Thankfully, Howard's fighting days appear to be long over. But there are still other things you might not know about him. Check out the video above for a few more surprising facts about the filmmaker.
Ron's newest movie, "Rush," opens in limited release on September 20 and nationwide September 27.
