I have to say, speaking from experience, just because an actor starts out in a role in the workshop, they won't necessarily play it when it goes to Broadway.
I was very lucky. I left college, and Richard Eyre was in charge of the National Theatre. I was offered the lead in 'The Seagull' with no experience and went on to do five plays there.
Do I think the West End relies too heavily on star names? Yes, I do, and it can result in miscasting and sub-standard stuff. Not always, but occasionally.
Tim Robbins had real confidence in college. He literally stole actors from the theater department at UCLA to be in his plays. The department heads got so mad at him.
I want to carry a show, but there are not a lot of leading parts for people who are not celebrities.
I had to choose between American and British actors, and it didn't take me more than a second to decide: Russians are Europeans and should be played by other Europeans.
You fight for certain roles, and you realise they're being filled by television and film actors, because theatre is constantly fighting for survival and they need names and faces and ticket sales.
As an actor, particularly in theatre, you're trying to get jobs on TV; but you're also losing jobs in theatre to people who are on television.
