Kim Basinger is 50. Not that you'd know it by looking at her.

The stunning actress now has a starring role in Cellular, a thriller that opened in the US last week. The news comes as a pleasant surprise, especially considering how we often hear about actresses in Hollywood feeling left out once they get to a certain age.

So, how does Basinger feel about her younger days? 'I wouldn't be in my 20s [again],' she says, adding that, if she regrets anything, it would be that she was very naive. 'I could have just avoided a lot of things had [I not had] that naivete with people. But do I regret anything? Not a thing. I've been one of the luckiest people, one of the luckiest girls in the world as far as I'm concerned.'

Cellular starts off with a wrong number on a cell phone, calling a young man to duty when he hooks up with a woman in danger. The woman is trapped. She doesn't know where, but she could be killed soon. Whether or not the hero finds her depends on how long the battery lasts.
