Steven Spielberg's 1971 classic DUEL (originally an ABC flick of the week later given a theatrical release with some extra footage to bump-up the thrills and the running time) made other menacing-machine-movies inevitable and Universal turned to Theodore Sturgeon's 1944 novella for more of the same.
The 1974 TVM is seventy-odd minutes of a (swiftly diminishing) construction crew, having accidentally awakened an ancient alien entity somehow entombed in a half-meriod bit of space rock, being (very) slowly menaced by the mean-spirited machine. It's very silly stuff, completely lacking in menace despite the hardware-of-hate's success in offing the bumbling humans. Not even The Asylum would dare to remake this one.
Marvel rolled-out its own adaptation of the novella at the beginning of '74, presumably tipped-off that the TV movie was in production.
