Eva Green gets ''depressed'' if she is on a diet.
The 'Dark Shadows' actress was once told she had to lose weight for a role but found going on an all-soup eating plan made her miserable and she couldn't do it again.
She said: ''Before my first film, the casting director asked me to lose some weight, saying, 'On screen you're going to look much fatter.'
''I started drinking soups and then I was like, 'I can't do it, I can't go on a diet'. It's hell, it makes you very depressed - food is so important to me. I couldn't go on.''
Eva admits she feels like an ''ugly duckling'' in Hollywood, but would not undergo cosmetic surgery to improve how she felt about herself.
She said: ''It's not all about physique and how beautiful you look. In this business actors who have Botox or surgery make you very aware of age. It's awful. In Los Angeles, I feel like the ugly duckling, like I'm from Venus or something.''
The 31-year-old star admits she is constantly on the look out for more ''ballsy'' roles because so often beautiful women are only cast as the girlfriend.
She added to InStyle magazine: ''It's so boring to play the girlfriend. Most of the women in film are there to be beautiful to the man. It's quite hard to find a ballsy or complex character. So the roles I've taken are those. Lot's of people put me in the dark category.''
