I do the final fitting because the client wants me there. They're not spoilt, they really understand that you're very busy, but they just want you to say what you think - for just ten minutes. They really want to know your opinion because it really is a service at the end of the day, a luxury service.
I am not an insecure actor, and this reflects in the films I have done. Yes, there was a phase when I was adamant on solo hero roles, but that is over now.
