The four movies I can remember seeing as a kid were 'The Elephant Man,' 'The Magnificent Seven,' 'The Good, The Bad and The Ugly' and 'Mad Max!' Two of those are westerns. So the western genre is emblazoned on my memory from childhood, and those are two great movies.
I don't want to be known as someone who is deliberately trying to do things that are not commercial! That is not a good reputation to have when you're trying to be a working actor.
I just gave up on acting for a couple of years until Good Will Hunting came around, and since it was Gus, it was hard to say no.
