Jennifer Connelly would never ''torture'' herself to be considered beautiful.

The 'Requiem for a Dream' star refuses to chase Hollywood ideals of what is considered good looking, as she thinks they would make her go crazy.

She told Allure magazine: ''The thing that really matters to me is well-being and happiness. Maybe it comes from knowing people who have tortured themselves trying to meet these strangely narrow and rigorous definition of what our culture thinks is beautiful.''

The 43-year-old actress, who is married to fellow movie star Paul Bettany, also talked about her on-screen chemistry with Russell Crowe, who she appeared alongside in 'A Beautiful Mind' - for which she won a Best Supporting Actress Oscar - and has reunited with for two forthcoming projects, 'Noah' and 'Winter's Tale'.

She said: ''We have an easy intimacy. We act together like the best kisses. We both bring equal passion.''

Jennifer - who has Agnes, two and Stellan, ten, with Paul, as well as 16-year-old Kai from a previous relationship - also recently worked with her husband, who directed the film 'Shelter', in which she plays a homeless woman.

She joked how being so close to the filmmaker has certain advantages, saying: ''One couldn't feel more safe as an actor knowing that the director's your husband. It's like, if I really make a fool of myself, I can just say, 'Honey, can you please not put that in the movie?' That was a great perk.''
