'Nymphomaniac' star Shia LaBeouf has raised concerned about his well-being after he attended the Berlin premiere of the film wearing a cut-out paper bag over his head that read 'I am not famous anymore'.
He has been tweeting the line daily since January when he was slammed for plagiarising a graphic novelist's work for his short film.
LaBeouf, who is promoting 'Nymphomaniac' at the Berlin International Film Festival, earlier arrived sporting a shaved-down tooth and disheveled appearance for the cast panel. During the conference, he answered just one question before making an exit.
When asked how it felt to be in a movie with such explicit sex scenes, LaBeouf said, "When the seagulls follow the trawler, it's because they think sardines will be thrown into the sea." The actor, 27, then thanked the audience, got up and left.
It was a reference to a situation with soccer star Eric Cantona from 1995, in which he spoke the same exact quote prior to walking out of a press conference, said the Hollywood Reporter.
LaBeouf's costars, including Uma Thurman and Christian Slater, looked stunned by his sudden departure - although they recovered quickly with a joke.
"Obviously, the script is packed with a lot of sardines. One sardine after another," joked Slater.
LaBeouf has been behaving strangely for over a month now, often getting in verbal as well as physical fights.
He also reportedly lunged at three men that tried to take a photo of him Saturday night. His most recent fight was in a London pub.
