I was surprised this disappeared the way it did and that Julie Andrews did not receive an Academy Award nomination. It's a tough uncompromising depiction of what it's like for someone who is losing control physically and starts to lose it emotionally as well. The scene in the back of the car where Andrews and Alan Bates argue and he goes that one step too far is unlike any personal altercation I can recall seeing on film. I found the film totally engrossing and very moving.
