Steve May, Effects Supervisor "We're responsible for anything that's animated that's not a character or a set. So we do waterfalls, dust clouds, the cracks, smoke, skid marks, sparks, explosion ... If Mater is doing spit bubbles or drooling or any other bodily function that's us too. I joke sometimes that we're the smoke, dust and bodily functions department on 'Cars.'"
