Phantom' was for me an interesting technique of telling the story. You have one voice that it is in the present telling what is happening, and then there's one voice from the past that's also driving the story forward. And you know that the two story lines will meet eventually.

I think I was righteous. I saw myself as the good guy in my own movie. I didn't get into many fights when I was younger, but when I did, they were righteous. I always thought I was defending something good. I fought for friends who couldn't fight for themselves. I was still being selfish and arrogant, but I was focused on what was fair and unfair.

When I was a teenager, my father went bust. He could have declared himself bankrupt, but he was an honourable man and he insisted on paying back all his debts. That almost ruined the family.
