Julianne Moore never intended to take on so many nude roles.

The actress - whose character in the new erotic thriller 'Chloe' falls in love with the prostitute she commissions to spy on her husband - said she doesn't really understand why she ends up naked in so many movies, but thought it must be because she is always attracted to love stories.

She said: "It's not like I ever intend to! I never do. I think it's happened a lot of times because I'm involved in things that are love stories. There are times when I feel it's absolutely not necessary at all."

The 49-year-old American star - who infamously made her name naked from the waist down in Robert Altman's 1993 movie' Short Cuts', and has also shed her clothes in 'Boogie Nights' and the recent 'Savage Grace' - said she still gets nervous about stripping off.

She told the Daily Telegraph: "It made me nervous. It's tricky stuff to do... Honestly, unless you're in Catherine's decisions every step of the way, then yeah, it can be prudent or salacious. Obviously there's something inherently dangerous about doing a scene like that, but it was all very deliberately staged, we watched playback, we were able to adjust things."

'Chloe' is released worldwide in March.
