The reality is that every movie is a new business. Nobody says, 'Hey, let's go down to the Pantages Theater, I hear a Warner Brothers picture is playing there.' Or, 'Let's go to this theater, I hear the film came in on budget.' It'd be ridiculous.
The minute you start the process of deciding to make a film and you're communicating that vision to anyone, you're in the process of selling. If you don't understand that, you're not in show business. You're just not.
