Helena Bonham Carter has advised Hollywood colleagues to start acting their age and leave young roles for "actual 20-year-olds". The British beauty, 40, is fed up of seeing mature actresses spend hours in make-up to play glamorous young women on screen, insisting older roles are more interesting. She says, "It's ridiculous. We're all going to age and we have to start learning to accept it. I recently made a film called CONVERSATIONS WITH OTHER WOMEN and loved my character. "She was a genuinely three-dimensional woman who was allowed to be in her late thirties, which is so refreshing in a world where people consistently try to be younger. "We aren't all 20 so why should we play parts where we're trying to look it? There are actual 20-year-olds to do that."
