In the area surrounding a US air base in Canada, something mysterious and sinister is happening: some of the local folk are discovered dead, minus their brains and spinal columns! The thumping heartbeat sound effects as the terror approaches adds an effective level of atmosphere to the scenes.
The already uneasy relationship between the military and the locals worsens, with the finger of suspicion pointing towards the air base. In steps Major Jeff Cummings (Marshall Thompson) to investigate, as the paranoia and unrest grows. The first three-quarters of this 70-minute movie gradually builds up to an entertaining climax, where the "unseen terror" eventually reveals itself in all it's glory, an effective spectacle, thanks to the pretty impressive (for 1958) special effects.
An unremarkable but decent and enjoyable 50's sci-fi B-movie, the performances are OK. Kynaston Reeves is good as the elderly and eccentric mad professor. The movie also stars Peter Madden, Terry Kilburn, and Kim Parker as the Major's romantic interest.
A cult classic from director Arthur Crabtree, deserving of it's status (thanks in no small part to the aforementioned special effects).
The black and white picture quality on this Partner Entertainment (BBC) region 2 release is a let-down, thanks to it's very grainy appearance, the sound quality is generally OK. The disc includes English subtitles.
