I’ve been trying to study a little bit more about facial animation lately, and I realized how complex simple things like eye darts can be. There are a few reasons why our eyes dart around. One of them is to help organize the thought process. For example; in a conversation, when asked a question, most people need a split of a second to process the information, think about the answer and talk back. It’s almost like our brains are not wired to multitask (keep eye contact and think about an answer). This video is a really cool example of that:
Check it out, how almost every time James Franco is asked a question, his eyes move around before answering. It’s a very simple thing, but if an animator is able translate that to his work it could make a huge difference in a shot. I totally recommend watching this video and the others from this series.
