Trivia: The scenes of the metal sphere flying through the air were accomplished by having a professional baseball pitcher throw it across the set, then running the footage backwards.
Trivia: The iconic bladed sphere presented a constant problem with lighting due to its reflective surface. Even with the lights on it cranked up to max it still didn't look sufficiently visible on camera, and no-one could figure out a solution, until they eventually brought in a specialist who took one look at the setup and yelled to the crew "You don't light the sphere! You light what's being reflected in it!"
