Is this the one where he unveils one of her breasts?
About 15 years ago when I was a kid I caught on TV a scene from a movie in which a white young ballerina/dancer was attracted into a dark corner of the stage by a masked man who starred at her and then approached her, unveiled one of her breasts, he touched it with his hand, and then he pulled back into the dark and disappeared, leaving the girl uncovered and confused. I remember there was something erotic/sexual about this particular scene, or at least that's the way I perceived it at the time.
Is this the film??
