Claude Rains tops the cast list in this Italian science fiction movie, originally titled Il pianeta degli uomini spenti, as a crotchety old scientist whose predictions about a looming astronomical threat to the world are at first disregarded, though he is called upon to help when a planet that had seemed poised to smash into the Earth instead enters orbit and launches attacks instead. Rains is entertaining in his over-the-top role, but the rest of the picture is fairly standard stuff.
Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
Movie 245 for 2021.
