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 »

The dangers of brining a rock with you while you go spelunking graphically portrayed!!!
2 April 2011 | by Aaron1375See all my reviews

I have been trying to see this film for years as I love to watch old obscure horror films. They do not have to be good or considered classic for me to hunt them down, I just enjoy watching them whether they be good, bad or ugly. Upon finally seeing this one, I have to say it has some things going for it, but overall it is a bit slow and underdone. The film at the beginning talks about this space pod returning to earth, we have an interview with the star female of the piece where we learn she is apparently psychic. She then heads to the ocean where she meets this guy who I have no clue who he is or what his purpose other than to introduce us to the fact that our heroine suffers from fears of monsters. We are soon treated to a scene with a mother and small girl that ends very nicely in one of the few good scenes of the movie. She then goes to the bowling alley to meet up with her fellow spelunkers and they proceed to have a long drawn out drive. They end up at a little place where outside one of the group finds a beautiful rock he just has to pick up. They finally make it to the cave where we get the privilege of seeing every member of the group repel down a line in the dark with their headlamp shining. They then pitch tents in the cave, which silly me, I figure all one really needs in a cave is a sleeping bag. Finally, after more cavorting in the cave the alien attacks and general mayhem ensues. Well not really, we are treated to every second of a rescue then a slow moving camera going across a body of a female and then some more cool stuff happens followed by another long stretch of nothing. You can see the problem, I am afraid the makers of this film were so enthralled with the cave that they forgot multiple times that they were supposed to be making an alien horror movie. There is some potential in this one, as there is a great kill involving a guy losing his head, also a nice attack on a couple as the cave seems to be alive. All the on screen kills are pretty good, just to much padding. The finale is particularly weak as we do not get to see any more cool deaths only a woman running from a point of view monster that at one point looked as if the monster was running from her. The makers of this film really did not seem to have a vision on what they wanted their monster to look like. Suffice to say at its best it looked like snakes, at worst hosepipe. More cool deaths, a faster moving story would have helped here immensely as would have a more climatic ending. Seriously, they showed nothing at the end to make the end cool. So just a bit of a bore for the most part with some very nice death scenes scattered here and there and a very nice topless shot of the lead girl. And you find out the best way out of a cave too, it is apparently to run fast, then in slow motion all at the same time to the point the fast you far surpasses the slow motion you.
