Did You Know?


After getting a cast, the direction was entrusted to Biagio Proietti, but after a week of various misunderstandings, he was ousted from the project. Ciro Ippolito therefore proposed the film to Mario Bava. However, Bava was already busy with another film and advised Ippolito to assume the role of director for Alien 2. Ippolito replaced Proietti a few days later, under the pseudonym "Sam Cromwell", which marked his directorial debut. See more »

I've done my best to track down the worst "King Kong" rip-offs in the world, now I'm doing the same for "Alien". And some of the copycat offenders of this one are awful. But the good news is - this one's not bad.

After a brief intro about the return to earth of a spaceship where all the astronauts were dead and/or hideously mutilated (or something), the main action of the film gets going with a group of people exploring an underground cave. Among them are people involved with the investigation of the spaceship, including a (slightly) psychic woman who senses the presence of...something.

The reason the film entertains is because of the well made scenes set in the cave. We follow the cavers through lots of perilous exploration, which starts off with the usual terrors of ropes snapping, long falls, dead end tunnels, etc, but soon starts to move into "Alien"-type territory as an unseen menace starts chomping on the cast! Scenes are well shot and there is some tension in the scenes all the while it is not clear what is actually going on. There's also some surprising gore as the characters die in bizarre ways. My only disappointment was that the extreme darkness of some scenes obscure a lot of what is going on, but generally the darkness works in the film's favour.

Bizarrely, the film does eventually leave the confines of the caves, but in a baffling change of location, the climactic scenes are filmed in...a bowling alley (?)! I can only assume that it is very likely that the bowling alley was known to the film makers and they got a very good deal for filming there - apart from that there is no possible logic behind the choice - it's really not a scary place at all! Things that work are: The acting - even with English dubbing, the performances seem quite good. The music - a cheesy "BUM-BUM-BUM-BUM synth score amused me greatly. The ending - which is as unexpected as it is unexplained, and finally the monsters: it's a case of less is more here, so don't expect to see any big rubbery creations.

Made on the cheap I presume, but a lot of the low budget is covered up by keeping the project quite modest. It's definitely better than "Galaxy of Terror". I'm please to say I own the UK pre-cert video which has a really nice sharp picture and is reportedly uncut. A modest DVD release would be nice...
