‘It’ is a Martian by birth, a Frankenstein by instinct, and a copycat. The monster dies hard, brushing aside grenades, bullets, gas and an atomic pile, before snorting its last snort. It’s old stuff, with only a slight twist.
Film starts some dozen years in the future [from 1958] with a disabled US rocketship on Mars. Only one of the 10 space travellers has survived, and a second rocketship has landed to drag him back to Earth where he is to face a courtmartial. The government is of the opinion the spaceman murdered his companions so he could hoard the food and stay alive until help arrived. But the accused swears the nine deaths came at the hands of a strange ‘It’-type monster.
Most of the film is spent aboard the second rocketship on its way to Earth, and, to spice up the trip, the monster has stowed away. It kills with a swat of its grisly hand, then sucks all available liquids from its victims.
None of the performances is outstanding. Ray ‘Crash’ Corrigan makes a fetching monster. Technical credits are capable.
