"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"

This quote by Gary Oldman talks to the trouble of playing a character that has actually currently been developed in the minds of readers. He acknowledges that readers have an unique connection with the writer, and that they will have their own idea of who Sirius Black is. He acknowledges that he might not be able to fulfill everybody's expectations, as it is hard to bring a character to life in a way that is real to the original vision. He knows that he may not have the ability to please everyone, however he is still willing to handle the challenge of playing Sirius Black. This quote reveals Oldman's respect for the readers and their connection to the author, in addition to his dedication to doing justice to the character.
