I came across this film while changing channels. What stopped me was seeing such a young Richard Basehart. What kept me was the tense story. Most of it was confined to the building ledge and the room behind it. The background film was extraordinary. I think I've been able to pinpoint within 2 blocks where on Broadway this hotel was supposed to be. Another thing was the cast.

It seemed like they hadn't gone for "stars", just good actors. Ossie Davis, Jeffrey Hunter, Howard Da Silva (before the black- list), and Grace Kelly in her first film. I wish I could see it from the beginning.
