Actor Ethan Hawke has vowed never to fix his crooked teeth because he doesn't want to blend in with other "fake" Hollywood stars.

The Training Day actor reveals he was once ordered to undergo dental treatment by a former agent to make his smile more presentable, but he refused.

Hawke admits seeing other famous names all looking perfect makes him want to stand out from the crowd.

He tells Britain's Daily Telegraph newspaper, "I watched the Oscars on Tv a few years ago, and they all looked like they were pod people. They looked so fake. And then crazy Sean Penn got on stage, and I thought to myself, 'There's a human being.' And people wonder why his heart is so beautiful and so transcending - because he's not afraid to be a human being. And I thought, I'm not going to fix my teeth...

"It's all vanity, any way you cut it. I just hate how homogenised people want us all to be. Nobody ever talks about Eleanor Roosevelt's crooked teeth, because she was a woman of substance. And we don't talk about how Mother Teresa would have been better if she could have lost 15 pounds, because she was a woman of God."
