Patty Duke Astin leads a formidable cast in this high-wire suspense thriller from the legendary producer of star-laden disaster epics, Irwin Allen (The Poseidon Adventure, The Towering Inferno). A cable car turns into a perilous death trap when an electrical storm stalls the sightseeing tram 7,000 feet in the air. Buffeted by winds that hamper their rescue, eight suspended passengers face a deadly night of terror dangling helplessly while the tram's weakened cable slowly starts snapping, one thin wire at a time. Featuring Cameron Mitchell, Bert Convy and Donna Mills, Hanging by a Thread is a hair-raising blend of excitement and danger that's good to the very last drop!
