"There are purists in computer graphics who are brilliant but don’t have the urgency about budgets and scheduling that responsible filmmakers do. I had to shake the purist out of them—essentially frighten them into realizing I was ready to use quick and dirty ‘cheats’ to get something on screen if they took too long to achieve it in the computer…I’d say, ‘You can build a flying saucer, or you can take a pie plate and fling it across the screen. If the audience only sees the pie plate very briefly and you throw it just right, they will buy it as a flying saucer.’ // I never did…throw the pie plate, but talking this way helped everyone understand that we didn’t have to make something that would work from every angle. Not all shots are created equal. Certain shots need to be perfect, others need to be very good, and there are some that only need to be good enough to not break the spell."
