I met with the filmmakers that Isaac London spoke to us about two weeks ago. What they are really looking for is people with their own costumes to play background Sith for a short scene involving a massive army of Sith. They weren't really looking for choreographers or anything else, but because I showed up in costume with props, had experience with choreography, and, most importantly, they had just lost someone, I got a supporting choreography Sith role. Based on the poor showing at the meeting, it is possible they may lose more people and need replacements, but I have the feeling they are looking for people who are reasonably experienced in choreography, are able to learn quite fast, and are able to commit a certain amount of time and energy to learning the part quickly. I may not have the time they are needing myself. I will keep you posted on progress. Please let me know if you are interested in a small background role. The color of your blade should not be a problem as it will be added in post production.
