Alan Rickman & Helena Bonham Carter Interview

How was it for you playing Severus Snape over this series, how did the books assist you?

Alan Rickman: J.K. Rowling lays out such a sure road map, there is what is right and what is wrong. You know what he wears sort of, you know what his hair is like, you’re told that he never really raises his voice, he doesn’t shout that much. There are rules to play, once you live inside those rules and you’re as focused as he is, in many ways it plays itself because the situations are so strong. Her grasp of her narrative is so iron clad that it’s not so much what you choose to do, as not disobeying it I think.
