Although it rather simplifies the issues at stake, this suspense thriller sustains remarkably well for over 90 minutes its central situation of a man threatening to jump off the ledge of a high-rise hotel. A formidable cast includes Richard Basehart as the disturbed man, Paul Douglas, Agnes Moorehead (in a typically fierce role), Robert Keith, Barbara Bel Geddes, Debra Paget, Jeffrey Hunter, Howard da Silva, Frank Faylen and - in her screen debut - Grace Kelly.
