Actor Shia LaBeouf is willing to do just about anything for his acting career, including tripping on acid to prepare for his new film, “The Necessary Death of Charlie Countryman,” which recently debuted at the Sundance Film Festival.

Shortly before the film’s premiere at the Eccles Theatre, LaBeouf talked with MTV News about his unusual preparation for his new film role.

“I’ve never done acid before,” the “Transformers” actor said, adding, “I remember sending Evan tapes.”

“Not like I would know about these drugs,” said Evan Rachel Wood, who was being interview at the same time.

“Not like she’s the expert on set. I’m just saying you reach out to friends and you sort of gauge where you’re at. So I was sending tapes around,” LaBeouf told MTV News. “I’d get 50 percents from people, and that starts creeping me out, and I got really nervous.”

By the end of his rehearsals, Wood said that LaBeouf was “spot on.”

“Well, yeah. But not because I’m wanting to be on drugs. I’m not trying to mess with the set or anything like that. It’s really just fear that propels people,” LaBeouf added.

LaBeouf isn’t the first actor to go above and beyond in order to get into character. Wetpaint, which has compiled a list of “22 Unbelievable (and Crazy) Movie Transformations,” notes that Rooney Mara cut her hair, bleached her eyebrows and pierced her nipple, nose and eyebrow to transform herself into Lisbeth Salander for the American version of “The Girl With the Dragon Tattoo.”

Some actors lose a lot of weight to play their characters. Anne Hathaway, for example, lost 25 pounds to play Fantine in 2012’s Les Miserables. To lose the last 15 pounds, Hathaway reportedly ate two thin squares of dried oatmeal paste a day.

Despite other examples of drastic weight loss and body modifications, Labeouf’s acid trip is probably one of the more risky ways to prep for a new film role that has ever been attempted.

LaBeouf’s acid trip, however, may not be the most head-turning way that the actor has devoted himself to his craft. To earn a spot in Lars von Trier’s upcoming movie, “Nymphomaniac,” the “Even Stevens” actor sent his personal sex tapes to the director.

“I sent videotapes of me and my girlfriend having sex and that’s how I got the job,” the actor said on Chelsea Handler’s E! network show last year.

LaBeouf also told MTV News that he’d be willing to have real sex on “Nymphomaniac” if Lars von Trier requested it.

Should LaBeouf have found alternative ways of preparing for his role in “The Necessary Death of Charlie Countryman?” What would you be willing to do to prepare for a job? Sound off in the comments section.
