A marvelous suspenseful, tension-filled, atmospheric thriller with absolutely NO "blood and guts," and I thank God for that. This film is intelligent in every respect and requires the viewer to watch with his/her brain switched "ON." "Night Must Fall" is the epitome of an intelligent horror film.
The first time I saw this film I was initially and completely mesmerized by Robert Montgomery's performance. I had not seen him act in any film other than gay '30's farces (with some serious roles thrown into the mix) or WW II films. I always enjoyed his films, but after seeing "Night Must Fall" I began to pay attention to his acting in other films and developed a greater appreciation for his skill as an actor.
Rosalind Russell is a talented, gorgeous actor/wit/comedienne, and is able to fully-utilize her skill in her role. What can I say about Dame May Witty, other than I wish I could travel back in time to see her on the stage in London in her prime. The two other women characters in the home, the cook and the girlfriend/servant, are small but vital roles that each actor plays to perfection.
Additionally, this was that unusual and rare film that was adapted from a stage play BUT was not merely shot as a play. Unless you paid attention to the credits, you would not realize this was a stage play. Not so easy to adapt a stage play to film, keep the dialog flowing properly, turning the play into a film that is meant to be seen as a film.
This film is perfectly written, directed and acted. The lighting and cinematography are superb. The set designs, costumes, etc...............all nonpareil.
