All I can think of is her movie I Dont Want to Die about a female inmate sentenced to be executed ...
I loved her in Back Street. I thought Susan Hayward and John Gavin were perfect.
When I was in college a few years later I recall picking up a biography of her that had just been published. I was just skimming through it at the University Bookstore, and noted at the end a recounting of her last days and the experience of the folks who went to see her one last time. The description of her was very disturbing and the apparent facts disclosed were upsetting. I put the book back on the shelf and wondered why any biographers would have included this. Then a few months later the two authors were on some talk show (this would have been Merv Griffin's wheelhouse) and the minute they came out and spoke you realized that these were these flaming queer adulators of glamourous stars. And while they professed to be such fans of hers they capped their book with a rather nasty recounting of her condition at the end. Totally unnecessary. But, as they were gay, maybe they resented her and included that section to cut her down a notch.
I know the movie you are referring to,but I think its titled “I Want To Live.”
Carol Burnett did a memorable and hilarious send up on her show, but I can't find a clip.
