Shia LaBeouf shows off his buff physique for Interview Magazine's latest issue. He talks with Elvis Mitchell about his dark upbringing and, among other things, that now-infamous run-in with Alan Cumming:

LaBEOUF: …Really I'm gaining control over myself again. I've given up so much control over myself to this industry. I felt like a slave who wasn't allowed to read. That's extreme, but it really is that debilitating when you have no say over it anymore. A lot of my actions in the public—and not all of them, because there have been some straight-up mistakes, like grabbing Alan Cumming's ass and getting arrested in New York at Cabaret.

MITCHELL: Was that about you walking into a theater and turning it into a performance space?

LaBEOUF: I was reading about [pioneering performance artist] Allan Kaprow happenings, and performance art of the '60s and '70s. So I thought, "All right, I know a little about that." We're all involved here. It's not just you on your stage. We're all in here and we're all part of this. I was wrong. The New York crowd didn't see it the same way, and I totally understand that. So I see the error of my ways. But that moment actually saved my life, forced me to look at myself. And when you're in a cell with a f–king mask on your face and a lead jacket, you can really see that some of your life choices were skewed wrong. And for some people it does take that. I still am a very stubborn, hardheaded person who is theatrical by nature. […]

LaBEOUF:…That's partly what I've been doing for the last year, trying to reinvent myself, in very calculated behavior, and sometimes in very uncalculated behavior.

MITCHELL: What would be an instance of the uncalculated behavior?

LaBEOUF: Well, like, grabbing Alan Cumming's ass and being a drunken buffoon in New York. But the way it gets construed in the media, I have no control over.
