I found this great reference vid of Michael Jackson the other day when I was searching for information on the 'The California Raisins'. As it turns out, the footage was posted by animation supervisor and stop-motion whiz Webster Colcord who I've had the privilege to work with on past shows. I emailed him about the video and he said that it was performance reference for two shots he animated on the project. To the right are a few pics from the production that Webster sent over. The 'Raisins' were produced at Will Vinton Studios. You can read more about the history of the studio here: History of Will Vinton Studio.
