My only conclusion about structure is that nothing works if you don't have interesting characters and a good story to tell.

Billy Crystal knows how to make people laugh. He's got 30 years on stage... there's no telling him what's funny.

Ive never been a big believer in ghosts or the spirit world, and for me, that was part of the point of the movie, ... What the Ghostbusters represented was the triumph of human courage and human ingenuity. People create their own monsters. Our fears come from within us, not outside.

We are all several different people. There are different aspects of our nature that are competing.

The cutting room is where you discover the optimal length of the movie.

I have tons of rescuing fantasies based on the movies I saw when I was growing up. I wanted to be Robin Hood and the Three Musketeers and the Scarlet Pimpernel.

I always think that the writer is doing the vast majority of the director's work, in a sense. If you're a writer who is also going to direct, you're doing all your preparation: You're already visualizing everything, you're imagining how the lines are going to be read, you see the blocking in your head, and you know the rhythm and the pacing.
