KIRSTEN Dunst revealed at the premiere of her new film Melancholia that she and director Lars Von Trier shared their own experiences of depression.
The 29-year-old actress - who stars in the film as bride Justine, who is struggling to enjoy celebrating her wedding while at the same time planet Melancholia is heading towards Earth - attended the premiere at the Curzon in London's Mayfair.
Dunst, who sought treatment for depression in 2008, revealed on the red carpet: "Lars opened up to me about his experience with depression and that in turn helped me open up."
The Danish filmmaker was declared "persona non grata" by Cannes Film Festival organisers over comments he made at an event to promote Melancholia, telling reporters at a press conference he was "a Nazi" and could understand Hitler.
But Dunst revealed how much she enjoyed working with him as he created such a nice environment on set.
She said: "I would have done anything with Lars. I adore working with him. There's no one who's communicated emotion so simply and effectively to me than Lars. And he's funny and a joy to be around."
Dunst revealed the mostly female set helped her to play the troubled character.
She said of Von Trier: "We get along really well. Mostly the people around him, producers, costume designers, are all female so it was a very nurturing set to be on. So I felt very free to be vulnerable in that environment."
She added: "He doesn't like to talk much and I appreciate that. I like people who know to put a certain chemistry of people and let them go. So to me the environment he creates really makes the film."
John Hurt, who plays Dunst's father in the film, also attended the premiere, which co-stars Alexander Skarsgard, Charlotte Gainsbourg and Kiefer Sutherland.
