Shia LaBeouf At Sundance: 'Charlie Countryman' Star Talks About Dropping Acid For New Film (VIDEO)

Shia LaBeouf dropped acid while working on "The Necessary Death of Charlie Countryman," but it wasn't because he "wanted to be on drugs."

The film -- which debuted at the Sundance Film Festival -- tells the story of a young man (LaBeouf) who heads to Romania after the death of his mother (Melissa Leo) and subsequently falls for a dangerous young woman (Evan Rachel Wood). During one sequence, LaBeouf's character takes hallucinogenic drug, which is what prompted the star to try it himself.

"I'd never done acid before. I remember sending Evan tapes. I remember trying to conjure this and sending tapes. And Evan being like 'That's good, but that's not but, that is,'" LaBeouf told MTV. "You reach out to friends and gauge where you're at. I was sending tapes around and I'd get 50 percents from people and that just starts creeping me out. I was getting really nervous toward the end. Not cause I wanted 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's trip was first reported back in August of last year. In an interview with USA Today, LaBeouf revealed that he dropped acid for "Charlie Countryman" as a way to fully immerse himself in character.

"What I know of acting, Sean Penn actually strapped up to that [electric] chair in 'Dead Man Walking,'" LaBeouf said to USA Today's Andrea Mandell. "These are the guys that I look up to."

"The Necessary Death of Charlie Countryman" is just the latest indie film with LaBeouf as star. The former "Transformers" franchise fixture also appeared in the 2011 film "Lawless" and co-stars in Lars von Trier's sex drama "Nymphomanic." That film was supposed to include real sexual encounters between the actors, but co-star Stellan Skarsgard told THR that the sex will be simulated, with body doubles and digital effects used to replicate the acts.
