I think cinema, movies, and magic have always been closely associated. The very earliest people who made film were magicians.
The screen is a magic medium. It has such power that it can retain interest as it conveys emotions and moods that no other art form can hope to tackle.
People on the outside think there's something magical about writing, that you go up in the attic at midnight and cast the bones and come down in the morning with a story, but it isn't like that. You sit in back of the typewriter and you work, and that's all there is to it.
