Actress Rachel Weisz believes that there is a pressure on women to be likeable in Hollywood.
The 45-year-old actress, who posed for the cover of Harper's Bazaar magazine, believes it is a modern problem.
"I've noticed in my career this tendency towards wanting women to be likeable in a way that's not asked of men.
"I don't understand how that's happened. You know, if you look back at Barbara Stanwyck, Bette Davis - they were difficult, difficult women, and they were iconic and worshipped.
