The joy of acting for me is to be able to experience emotions in a safe environment. You can't scream and cry in the street because everybody will look. If you do it on a movie set, you get applauded.
A choreographer deals with the movement that you create, and with a creative director it's about the story, the stage, the lighting, the costuming, executing someone's idea, choosing how far to go or how little to go, and blending it so that you feel it, you're emotionally effected.
I like when the song starts to take over and you feel like you have to dance more than write.
