Before the production of Ice Age 4 began, I had the chance (and luck) to work with the Lead Characters to help create the coolest bad guy in the movie, Captain Gutt. For me, pre-production is the best part of the movie making process - the time to define personalities, try different things, explore, invent, discuss, propose, whatever your imagination may offer to make the characters great! Of course, throughout this process some ideas make the final cut, others don't. The greatest reward is being a part of this process.
Here are a couple animation tests I made to explore/define Captain's Gutt personality.
