A huge part of acting in movies is appetite. You do your best work when you've got a lot of appetite and you really want to embrace something. When you get tired, you don't have that hunger.
For me really good acting is about subtext.
Acting is all about likability.
When I was younger, people used to say you only really prove yourself as an actor on stage. And I disagree with that. Some of the finest acting I've ever come across has been for film.
