She probably had a lot of risk factors to have a heart attack, and it happened to come on her when she was particularly emotionally involved in the movie. It is sad, but when you think of the millions of people going to millions of theaters every day, I'm sure it does happen elsewhere. This is only in the press because of the subject content, I'm pretty sure.

As for myself, I won't be going to see it.. I'm way too sensitive and upset by such things. Braveheart was also a great movie, but I felt physically ill after watching it and disturbed for days after seeing it. I think I understand how horrible it is without a Hollywood depiction to traumatize over. That's just how I am though.
