I don't really know who I am as an actor: the best thing would be to experiment with it for the next 30 years and never really find out.
When I finish a film, I like to drastically change my appearance. I get sick of looking at the same thing in the mirror for months at a time. So when a film's over, I'll do something like shave my head.
Actually, I think it's quite sensible not to take yourself too seriously.
