Shia LaBeouf sent "sex tapes" to director Lars von Trier to get his role in Nymphomaniac.
The 26-year-old actor claims he showcased a different aspect of his talents to the filmmaker by sending him intimate footage of himself and his girlfriend in order to land a role in the forthcoming movie, which is expected to include scenes of real sex.
Speaking on Chelsea Lately, he said: "I don't know what it's gonna be until I get out there.
"I know he's a very dangerous director, I know we're trying to do something different. It's not your typical film. It's about what it's about.
"I sent him videotapes of me and my girlfriend having sex and that's how I got the job."
LaBeouf has previously said von Trier will make the cast do everything "for real" in the movie, and anything too explicit will be "blurred".
He said: "[The movie] is what you think it is. It is Lars von Trier, making a movie about what he's making. For instance, there's a disclaimer at the top of the script that basically says we're doing it for real. Everything that is illegal, we'll shoot in blurred images. Other than that, everything is happening."
Two versions of the film, with one more explicit than the other, will be released.
