Theatre has always been better disposed to colourblind casting than telly or film. Given that most television is contemporary, and it reaches 56 million people, I am disappointed there still isn't more representation.

The worst moment in my life was when I was seven years old and I discovered that there was a thing such as racism. You don't know you're different until someone lets you know.

I've always felt I had to prove myself, and now it has become second nature. When I first went to university, I took lodgings with a woman who said, 'What are the chances of you staining my pans?' I said, 'I don't think I understand the question...' and she said, 'When you cook your curries.'

I sense a kind of fear of writing black or Asian characters from non-ethnic writers, who perhaps feel that they don't know the culture and therefore can't write about it. By and large, if there's an Asian character, I might get a call. But if the character is called 'Philip,' the chances are I won't.

Because of my Asian-ness, I couldn't be anonymous - what I said, what I ate, what I did at the weekend were startlingly different to what everyone else did. I was also a performer, quick and chameleon-like, good at accents, so that made me stand out.

On a radio drama I'd like to feel that I had just as much chance of playing Mr Darcy as anyone else because I can sound like him, yet many radio producers find it very difficult to extend their imaginations to employing anyone who's non white.

I make terrible jokes every time I go into a hospital. I think it's a defence mechanism.
