This is no CREATURE FROM THE BLACK LAGOON, but I had extremely low expectations going in. The movie was a little better than I anticipated, but not by much.
The film concerns two journalists who realize there is something amiss going on in the waters off of Japan when they view an informational film done by the military and see something that they shouldn't. When they try to investigate, they unwillingly become part of a mad scientist's master plan to build and rule an underwater kingdom.
There are a variety of actors in TERROR BENEATH THE SEA, both Japanese and non-Japanese. Most of the film is dubbed which can always lend itself to overacting a bit - there is no exception here. I also found that the roles were somewhat one dimensional - the mad scientist was the stereotypical mad scientist (complete with dark sunglasses), the lead female was the stereotypical woman from the 60's (outside of having a job) who looked to her man to save her and whined and cried a lot, the military guys were as formal as you would expect, etc. The monsters were fairly well done for the time and not as bad as some others I've seen but their costumes were obviously cheaply made. Interestingly, throughout most of the film they are programmed to act in a certain way, but towards the end, they have a mind of their own.
The plot line is rather slow and the special effects were really saved for the end of the film. There are lots of underwater explosions that were actually pretty well done for the time although some other reviewers would disagree. The other effects were really chintzy though. The soundtrack was the typical "mod" type common in the 1960's.
This is really a movie for either kids or fans of old Japanese monster movies. I wouldn't be able to recommend it to a horror fan.
