You get used to being lazy doing films, but classical theatre's going to finish me off.
People are out of their home on a Saturday night or they're at the movies or they're at dinner and a lot of the people who flip on the television are doing just that. They may have never seen your show before and you can't count on to your audience to be there week in and week out.
Experience is the best teacher of all. And for that, there are no guarantees that one will become an artist. Only the journey matters.
