In computer animation, every detail has to be thought out, designed, modeled, shaded, placed and lit. The more you add, the more computer memory you need.
John LasseterIt [moviemaking] is about entertaining audiences with great characters and great stories, you want to make people laugh, you want to make people cry, you want to have great music that is memorable. You want a movie that, as soon as it's over, you want to watch it again, just like that. That's what it is, whether it's live-action, animation, hand drawn, computer, special effects, puppet animation, it doesn't matter. That's the goal of a filmmaker.
