Well, the movies introduced me to Harry Potter. I wasn't a fan at first, but as soon as the film version of Prisoner of Azkaban came out, I got hooked. And that's what I love about the movies - they have introduced people to the HP series and have introduced them to the books too, resulting in the very large fan-base. Obviously there were fans before the films were released, but I do legitimately think that the films have done an excellent job at creating JK's magical world. Long live Harry Potter, I say.
