Kirsten Dunst has gotten "angry" when she has been made to feel like a "puppet" on movie sets.

The actress - who has had leading roles in numerous films, including 'Spider-Man' and 'Marie Antoinette' - admits she has struggled to work with some directors, but her recent experience shooting 'Melancholia' with Lars Von Trier was not like that.

She said: "I've felt like a puppet on films before and have been really frustrated and angry.

"I mean, Lars might see himself as some master manipulator but that's not how he comes across. I mean, most of the scenes were improvised and he doesn't even say that much. How can that make me his puppet?"

Kirsten's breakthrough role came when she was just 10 in 'Interview with the Vampire' as bloodsucker Claudia, and she admits working with Tom Cruise and Brad Pitt on the movie was both educational and fun.

The 29-year-old star said: "It never felt like work, that's for sure. Brad and Tom treated me like their little sister, their little princess. But I think children handle things better than adults. As an adult, you get insecure. You're tired, you're worried about how you look and what it all means.

"When you're a kid, you just think, 'Oh I like my dress. Let's go and play!' "
