Watts bound for violent scenes

New mum Naomi Watts really did struggle while making violent new movie 'Funny Games' - because she was actually bound for torture scenes.

'The Ring' star admits she didn't have to act out scenes in which she was uncomfortable and humiliated - because she was in a state of panic for real.

Playing a mum and wife, who is tormented and tortured by two psychotic home invaders, Watts was tied up in her underwear for half of the disturbing Michael Haneke film.

She recalls: "It was very, very hard to do and the fact that I had to do the rest of the film in my underwear was incredibly difficult but it helped me in a way get closer to the tension and the vulnerability and that feeling of utter violation.

"I was properly bound up… I literally could not move. There were no sort of slipknots or cheating. I found myself going: 'I can't do this. I'm incapacitated', which added to my frustration and emotion."
