You'd be surprised how many TV & film actors are magicians but think about it, Who's the President of the Magic Castle? Who was on the founding board of the Castle?
The first time my parents came to visit me in L.A. I took them to brunch at the Castle, it was one of those very odd times when about a dozen major celebrities were there. It was so prolific that my father insisted we leave and go "somewhere normal to eat" so we left and went to a Denny's on Sunset Blvd. where it literally ran into another noted actor from yesteryear fame.
LA is a weird place to live. Literally everyone who shops at Trader Joes (grocery store here in the US) is either an actor, a celebrity, or just gorgeous. It's aggravating how gorgeous everyone is here. Kidding. Kind of.
The Magic Castle is a huge draw for celebrities - I've seen Zach Galifiankis, Lindsay Lohan, Eli Roth, I even did my show in the Close-Up gallery for Aziz Ansari once.
I'd agree that magic is either a heavy fascination or side hobby for a lot of Actors - NPH, of course, Harry Anderson, Steve Martin. Just in this week's Expose we mentioned an article in which Rick Rubin, huge producer for almost every famous musician, talks about his love for magic.
Any other magic actors come to mind for you guys?
