Transformers star Shia LaBeouf has denounced the Hollywood studio system.

Explaining his efforts to steer his career towards more independent films, LaBeouf - who is set to star in the upcoming Lars Von Trier film Nymphomaniac - has slammed what he believes is an inability to be creative in the big-budgeted film environment.

"There's no room for being a visionary in the studio system. It literally cannot exist. You give Terrence Malick a movie like Transformers, and he's f****d. There's no way for him to exist in that world," he said.

LaBeouf did admit, however, to regretting his negative comments on Indiana Jones and the Kingdom of the Crystal Skull (which prompted his co-star Harrison ford to call him an idiot): "He [Steven Spielberg] told me there's a time to be a human being and have an opinion, and there's a time to sell cars. It brought me freedom, but it also killed my spirits because this was a dude I looked up to like a sensei."
