I think it's her best acting performance too. I'll be watching that very uncomfortable movie again today. A fine movie, but, damn it's rough watching it.
Olivia really nailed this role of a woman sent to an insane asylum after a nervous breakdown. This movie has always been difficult for me to watch due to how mental health institutions were runned back then. Also, both of my grandmothers were retired nurses. One was the head nurse at the city jail and the other was a nurse at Fairfield Hills Hospital, a mental health hospital similar to the one portrayed in this film. You want to talk about some horror stories that my grandmothers told my family. That hospital in Newtown, CT housed thousands of patients back in the day before the state of Connecticut finally closed it down, many years after my grandmother retired. Anyhow, I have awful childhood memories of that freaking place based on some of those horror stories and the few visits I made there with one of parents to pick up my grandmother at work. As to the movie, why is it that every movie about such institutions has a sadistic head nurse?
Twilight Time's Blu-ray is another excellent release as noted in Matt's fine review of it.
