Did You Know?


The computer shown in use for the army's transmitter was actually an 80s home computer, manufactured by Commodore. It's either the C64 or VC20. They shared an almost identical casing design in the early 80s. The branding of the device used in the movie was taped over. See more »

I just finished watching this movie and I must admit I didn't have high hopes. To my pleasant surprise this turned out to be a quite good movie. It wasn't a great movie, but I am very glad I got to watch it! During a test of a low frequency transmitter two men and the transmitter disappear. A team is gathered to search the caves where the test took place. Caves that never before have been explored by man. But, what waits them below they could never imagine.

This story turns out quite original and I think that is maybe what makes the movie so good. The script is far from perfect, but it works. The acting is probably the best with the whole movie. It is generally good. The cinematography could, however, been better. I find it too boring. It's too straight. Though they did a pretty good job in creating the atmosphere and the mood. There were some pretty chilling sequences.

When it comes to effects what can you expect from a 1984 B-movie? Well, they did OK on most of it, except for the monster. It was actually pretty bad and in fact personally I think they should have cut the whole monster. They way I see it, it rather took then give anything to the movie.

I can recommend this movie because of it's story. There are few cliché there. As for the rest of this movie it is OK, but nothing out of the ordinary. However, well worth to watch.
