Shia LaBeouf is so committed to his craft, he's willing to do whatever it takes -- drink, do drugs, have sex -- in order to deliver as realistic a performance as possible.

For example: to prep for a scene in the upcoming "The Necessary Death of Charlie Countryman," the former Disney star, 26, says he took LSD in order to better relate to his character, who trips on acid during the Mob-focused flick.

"There's a way to do an acid trip like "Harold & Kumar,"and there's a way to be on acid," the outspoken thespian opined to USA Today. "What I know of acting, Sean Penn actually strapped up to that [electric] chair in 'Dead Man Walking.' Those are the guys that I look up to." (His Lawless director, John Hillcoat says although LaBeouf's strategies don't technically qualify as "Method," they are "Method-like.")

LaBeouf took his technique so seriously while filming "Lawless," a movie which takes place during Prohibition, that he imbibed as much moonshine as he could. (He later admitted his co-star and on-screen love interest, Mia Wasikowska, was so appalled by his drunken behavior she tried to quit the project.)

The "Transformers" actor also recently boasted he'll be having real sex on camera for Lars von Trier's new film, "Nymphomaniac."

"There's a disclaimer at the top of the script that basically says, 'We're doing it for real,'" he explained to MTV. "Anything that is 'illegal' will be shot in blurred images. But other than that, everything is happening . . . It's going to be a wild movie, man. It's going to be a wild movie."
