Shia LaBeouf is a compulsive Twitter oversharer and he has no qualms about getting naked. So it was inevitable that his twin passions would eventually collide. Yesterday, the star of Charlie Countryman, the movie in which he says he dropped acid to help tap into his character, posted a photo of himself from the film sans wardrobe. “Tune in, turn on, drop out,” LaBeouf wrote in his tweet.

Lately, LaBeouf has torn into roles in a very first-person way. For Lawless, he admitted to guzzling moonshine, and for the upcoming Nymphomaniac, he hinted that his graphic sex scenes would be 100 percent Shia. (Director Lars von Trier later revealed that body-doubles would be used.)

In Charlie Countryman, out Nov. 15, LaBeouf plays an American in Romania who falls for a young woman (Evan Rachel Wood) with ties to a violent gangster (Mads Mikkelsen.) Watch the trailer — with only hints of nudity — below.
