Juliette Binoche thinks watching porn is ''pathetic''.

In her latest film 'Elles' the French actress plays a woman who discovers her husband has been viewing X-rated movies and Juliette admits she can't understand why men do it.

She said: ''A lot of men take porn as not that important, not that serious, whereas women tend to take it personally. It's like, 'How can he make love to me after watching something like this?' I think the first time I was aware that ... (a partner was using porn) ... I was really shocked because I didn't understand it. Lovemaking for me is related to feelings, and sensations with feelings, and so when you don't have the feelings it becomes animal-like because you're not in touch with your heart. There's a sad and pathetic side to it.''

In the film, Juliette had to perform a masturbation scene and says she turned down the director's offer to act it out in private.

In an interview with The Independent newspaper: ''I said, 'No way, you stay with me and tell me all the stages you want. You wrote it, you face it, as I have to face it.' I had it in my mind that it should be like a painting, with expressions of birth and agony.''
