Danish director Lars Von Trier has described how depression has left him unable to work, and said he was unclear when he would make another film.
Von Trier won the Palme d'Or in 2000 for Dancer in the Dark
He had lost focus after being admitted to hospital at the start of this year, he told Denmark's Politiken newspaper.
It felt "like a blank sheet of paper", explained the 51-year-old, who is known for productions such as Dogville.
"It's very strange for me, because I've always had at least three projects in my head at one time," he added.
"You can't make a film and be depressed at the same time.
"They say that it can take a couple of years to recover after a depression - but let us see."
He also said he was unsure if he would be able to begin work on a horror movie called Antichrist, which he had planned to start filming toward the middle of this year.
The film depicts Satan, rather than God, as the world's creator.
"I assume that Antichrist will be my next movie," he said, "but right now I don't know."
Von Trier is known for creating the so-called "Dogme principle of film-making in the mid-1990s.
This banned props, lighting and sound editing, as a way of stripping down the production process.
