“I just mean . . . when I come up with a great idea for a film, it’s like being drunk. You know that giddy feeling you get when you’re psyched about something? It’s exciting because it’s all potential. But then you wake up the next morning and reality has sunk in. you start to wonder if the idea was really good as you thought, and you suddenly see all the holes in the plan, and that high from the night before starts to crash. That’s the hangover.”
