I've been the teenage success, I've been homeless and driving around in my car and not knowing where to eat. You just want to keep working and learning, and I was doing that. If I hadn't done 'Wild Bill,' I'm sure I would have acted in something else.

I've been lucky enough to do theatre, film, and television for a career. Unless I get offered a job as an astronaut, I won't stray too far from it.

I was turning up at sets where inexperienced people were making these badly written films - but they were doing it; that was the point. They were getting their films out there. And they were paying me, so they obviously had access to money. I just thought, 'I can make something better than this.'

It took me a long time to make that leap to being a grown-up and responsible adult because I carried on being a child actor into my late twenties. It's OK to be precocious when you're young, but when you're a man of about 27 or 28 and playing a 17-year-old in a TV show, it kind of prolongs your childhood.
