Hollywood bad boy Shia LaBeouf blames method acting for the wacky antics that got him fired from a Broadway play and tossed in the slammer says The New York Post.

The drama-prone actor was simply role-playing when he clashed with Alec Baldwinon the set of “Orphans” and also when he smacked actor Alan Cumming’s butt at a performance of “Cabaret,” he claimed in Interview Magazine’s November issue.

“Alec and I butted heads hard. I was sleeping in the park . . . At the time, I was out of my mind,” he revealed about preparing for the brutal, street-smart character, Treat.

“My whole goal was to intimidate the f–k out of Baldwin. That was the role. And it wasn’t going to be fake. I wanted him to be scared . . . So I went about doing that for three weeks of rehearsal,” he said.

The 28-year-old actor was arrested in June after drunkenly slapping Cumming and later spitting at a cop.

“I was reading about performance art of the ’60s and ’70s and so I thought . . . we’re all involved here. It’s not just your stage. We’re all in here and we’re all part of this,” he said. “I was wrong.”
