Shelley Winters 1920 - 2006
I haven't seen this version of the movie yet, but I hear Sylvia Syms does a good job.
That said, we need to recognize the original Belle Rosen, Shelley Winters, who passed away earlier today at age 85.
The underwater swimming scene was undeniably the highlight of the whole movie, and I remember reading somewhere that Winters and Hackman did most of their own swimming. Hope they give her an honorary Oscar at some point.
A legend is gone, but not forgotten. God Bless Shelly Winters and her family.
