A scientific experiment goes wrong, and soon the local doctor on an isolated island is faced with an odd corpse. He turns to a famed medico on the mainland for help, and a wealthy young woman inserts herself into the expedition to determine the cause of the calamity — and put an end to it. As events transpire, the villagers find themselves besieged by strange, deadly creatures. A fairly satisfying creature feature that manages to build suspense is let down somewhat by an unappealing lead (Edward Judd) but helped quite a bit by the presence of Peter Cushing.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 463 for 2021.
