Well, any movie buff will recognize here a pure tribute to Louis Malle's ASCENSEUR POUR L'ECHAFAUD, where a criminal is trapped in a jammed elevator just after he committed his murder. Even a blind man could recognize this, only by earing the dialogues !! And this TV movie made in 1974 is also in the line of the disaster movies wave, where we have some former Hollywood stars who happen to be put together in front of the "disaster" just after being separately presented. See AIRPORT, TOWERING INFERNO, POSEIDON ADVENTURE, EARTHQUAKE, THE SWARM and so on...And, it's of course a small budget feature, the perfect TV product setting, cheap and efficient. But not advised for claustrophobic people. And the character study is also interesting. Some unbelievable scenes, such as this one when Farentino's character, after threatening the people with him in the elevator with his gun, gets on the elevator roof without any problem, as if he had a ladder... It was aired in France in the late seventies.
