If the character has no eyes, such as an inanimate object like a Luxo lamp, it is even more important to lead with the head. The number of frames to lead the eyes and head depends on how much thought precedes the main action. The animator must first understand a character’s thought process for any given action. Consider a character wanting to snatch some cheese from a mouse trap; the eyes will lead the snatch by quite a bit because this is a big decision. The character needs time to think, "...Hmm...This looks tricky, is this cheese really worth it or is it just processed American cheese food?...Oh what the heck...," he decides, and snatches the cheese.
