I was a fan of Hitchcock, but more importantly than that, he is such an inscrutable man, and a very carefully inscrutable man. He apparently was blank-faced with a calm and controlled presence. I was immediately anxious and thought, 'How am I going to get behind that?'
There are things you do when you're writing that are so fun to do it's almost like they're private jokes that are amusing to you but no one else is going to enjoy them nearly as much and you worry you're going to have to take them out in the end.
