That's a real shame, although not unexpected. Since hearing about the movie, everything I've read about her suggests that she's one of those rare people that really does live on the edge. She seems to be the larger than life person that movies couldn't begin to create without seeming cliche, but that was it.
Given the recent legal issues and now her death, I wonder if they are thinking of adjusting the movie to account for them of leaving it simply as is.
