I don't often get embarrassed; having gone to school in the early 1970's, I can only recall being embarrassed twice when seeing someone else have sex. This was one time, even though technically that's not what Ms. Dunst's character was doing. She was just listening to music, but it was one of the most erotic performances possible. What made it embarrassing to me was that both the character and the actress were about 15. How did David Warry-Smith, the Director, communicate with her? "Say, listen, Kirsten, ah, well, you presumably have never done this before, but just pretend your having the most incredible sexual experience of your life, no, not just your life but anyone else's life. I'm sure you'll do fine." And then walk back to his stool and try not to die of embarrassment. And how did she do such an incredible job? That's a question I don't think anyone should know the answer to.
