Kim Cattrall: "I want to embrace ageing"

The 54-year-old actress said she admires people like Judi Dench, 76, and Annette Bening, 52, who have a successful career without feeling the need to go under the surgeon's knife.

'I look at people like Judi Dench, who's in her 70s, and I think, 'What the hell am I frightened of?,' she said.

'In my life and career I want to embrace ageing because I think that's what's interesting. I think a forehead without any lines doesn't tell me they've lived a life. '

The star, who played man-eater Samantha in the hit TV series, has previously admitted to using Botox on her forehead, but is too frightened to have surgery, saying in 2008: 'I don't want to look in the mirror and not recognise who's looking back.'

In her new flick Cattrall plays a veteran porn star who is stripped bare of make-up and her designer clothes. She takes on the role of a 50ish porn star called Monica Velour in Meet Monica Velour who becomes the object of obsession of a young fan.

Liverpool born Cattrall said she wasn't sure she could play the part of a woman living in a trailer park after being associated with such a glamorous character as Samantha.

'I didn't know whether I could do it, because to be that stripped of makeup, clothes, shoes, in Hollywood, you have to be beautiful,' she told the Los Angeles Times.

'You have to be desirable. And that's why so many woman of my age or even younger are pushed to Botox and plastic surgery, all the things that people say, 'Why do women do this?'Where do you go in your 50s in your career?

Cattrall said she has resisted having plastic surgery to turn back the years, but doesn't judge those who want cosmetic help.

'I think it's every woman's choice, not just every actor's,' she said.

'And I have no judgement about it. It's your body, your life. Do what you want to do.'

Cattrall said she had deliberately chosen roles that weren't as sexual as Samantha, including playing a secretary in Roman Polanski's thriller 'The Ghost Writer', to develop her career.

She said:' The career that I'm having post-Sex and the City has been about making different kinds of choices. I'm talking about Ghost Writer, My Boy Jack, Any Human Heart, the plays I've been doing in England, my objective was to take different kinds of roles, not just sexualized ones.

'And when this script came to me, I thought, 'Am I going back on that track again?' And I read it, and it was so well written, and I thought this is not just a woman who's been marginalized. She's an outcast, and she's a misfit.'
