I had looked at this thread before going to an audition for characters here in Paris, and simply wanted to share my own experience to put anyone who may be nervous at ease
My audition was today, April 15th, 2009 in Paris. We were asked to arrive at 9:30, but of course people were there much earlier. I got there around 9 and waited for half an hour on the street with about 100 other candidates. They let us in the building at 9:30, and we were asked to follow the woman in charge of the process into a large hallway, where we were given the opportunity to change if we needed to, and if not to simply go to the dance hall.
Most people were just wearing comfortable/gym clothes...think tee shirts, sweatpants and sneakers.
The first thing we were asked to do was to remove our shoes, and we were then measured in a long cattle call line for height. After that, we were given a form to fill out with our information (name, address, a few questions about experience). The woman running the interview asked if there were any non-French speakers at this point, and said it was absolutely not a problem if you don't speak French, and her assistant translated for the 5 or 6 people who needed it.
After the forms were filled out, we watched a powerpoint presentation about working at Disney in a character position, how much it pays, etc.
After all of that, we were asked to fill the center of the room, and asked to walk like a cowboy for eight beats. It wasn't a big deal, definitely not dancing...just movements and gesturing. We then were asked to act like a pirate for 8 beats, then be on the seven dwarfs, be an evil villain, and be a prince/princess. We did all of these little pantomimes in rapid succession, each one lasting for 8 beats. You definitely don't need any choreography experience to complete that. Just be BIG and ANIMATED.
We ran through it as a group three or four times, and then they called us out in groups of six to perform those character impersonations. Finally, we were called into sections for who made it past the first cut and who didn't. As I didn't, I can't tell you much else...only that the woman running it said that everyone needed to do the choreography session, even if you're not a dancer, because they need to evaluate each person on their abilities as a whole.
Hope that helps!
