It's always hard when you're playing someone for a lot of people out there who are going to see the movie after reading the books. There's a communion between a reader and the writer, so people will have an idea who Sirius Black is and I might not be everyone's idea of that.

Wanting to be a good actor is not good enough. You must want to be a great actor. You just have to have that.

You choose your friends by their character and your socks by their color.
