There has been a lot of criticism of Robert Mitchum in this film. I thought he was perfectly cast. I haven't seen this movie since I was a teen, in the 1960s. However, there were three scenes in the movie that moved me so strongly I can see them in my mind's eye all these years later. The first is the emotional scene when Olivia de Havilland can take no more of Mitchum's treatment and tells him to get out. She was so powerful and poignant. The second was when Mitchum was trying to revive Bickford and couldn't. Finally, the scene where he went back home, and de Havilland opened the door and Mitchum just stood there looking at her so pathetically. I just finished watching The Snake Pit and I'm going to go rent Not as a Stranger. She is such an amazing actress!
