Police had to remove Shia LaBeouf from the audience of Broadway musical “Cabaret,” Thursday night, after the “Transformers” actor reportedly went nuts, firing up a smoke, yelling and slapping people on their behinds and in the backs of their heads, according to the New York Post.

Sigh. Some people will simply never understand Shia LaBeouf’s art.

When police approached him in the Studio 54 theater around 9:30 p.m., he was “incoherent” and “very agitated,” law enforcement sources said. He reportedly tried walking away, but fell on his face.

The actor was taken to the police station, where he reportedly told officers, “I’ll (expletive) you up,” called one officer a gay slur, and had to be muzzled with a face mask for spitting, sources told the Post.

It’s as if he becomes his character … in this case, Alec Baldwin.

He also reportedly screamed at police: “I have millions and millions of dollars and attorneys. I’m going to ruin your career.”

Well, he was definitely ruining at least one guy’s career.

One police source said the actor smelled terrible and lied about being in the Army.

Right. Fighting pretend space aliens who turn into cars doesn’t qualify as being in the Army.

LaBeouf was charged with criminal trespass, harassment and disorderly conduct, according to the police sources. He was released Friday morning and is due back in court July 24, according to the Associated Press.

“Ladies and gentlemen, this is your places call for Act II. Also, to let you know, Shia LaBeouf has just been escorted from the building in handcuffs. Yep, that just happened,” cast member Danny Burstein wrote on Facebook, according to website Just Jared.

As you know, LaBeouf has a long history of strangeness and/or criminal behavior.

He was videotaped in January head-butting a man during a bar brawl in London, according to ABC. In February, he was seen at the Berlin Film Festival disheveled, with a paper bag over his head. He was arrested in 2007 at a Chicago Walgreens.
