I've always had a problem with people mixing reality with fiction, actually. It is currently irrelevant, sorry Keira, what age she was during filming because the the to make about that was them. If it was creepy, why accept the role? That was that characters biggest moment, really. Only real reason her story was included. Her pinnacle moment, in other words. The agents, the actors and actress, the directors, and anyone else involved with the production should have had the "creep factor" conversation them.

As for the screen in the fictitious world, it's a bad moment as far as I'm concerned because Juliet is a married woman. Married to Mark's best friend. That means DOUBLE off -limits!! That's why the scene is truly inappropriate. You snooze you lose.
