Alternate Versions

The US Broadcast version that was made by Sandy Frank in the early 1980s and was availible from Celebrity Video is missing certain scenes. Besides the original Toei logo and opening credits being replaced by Frank's credits, 2 scenes have been cut; they are:
  • 1. The part with the woman in the shower has a brief shot of nudity in the light before it mysteriously goes out.
  • 2. When Sawa pulls her friends remains into the raft, the US version cuts it so you dont see the body slung in; we only see it drop in.

This Japanese film really amps up the blood, but it is still rather dull in places.
4 February 2011 | by Aaron1375See all my reviews

This one had potential, unfortunately it moves so slowly that it kind of shoots itself right in the explosive tank. The film is about mysterious killings in a lake and does follow a basic 'Jaws' formula for the first bit of the movie. They wait awhile to reveal the beast then it is finally shown, killing a couple of guys who played a very bad prank. The film follows a man who wants to get to this area near Mount Fuji where there has been mention of a petrified egg. He thinks that perhaps there is money to be made from this discovery. Strange though that they mention this discovery as no scientist actually sees this, but rather a woman who falls into a cave and then runs from the forest in a panic and falls into a coma shortly thereafter. Why this makes the news is beyond me. Still, he gets there and there start to be strange incidents happening such as a horse with its head bitten off. After a bit the dinosaur comes in, chomps a few people and then near the end the bird of the title swoops in and makes an impressive first appearance. Of course, the two duel in a very unimpressive battle that made me lower my initial score of six to five. This one had potential, they just needed to have more bloody kills and less banter. Sure they were copying "Jaws", but this film was not going to be in that film's league as far as acting and atmosphere so you have to go the bloody route. They did, but not quite enough. They even managed to show the naked rear end of a lady, so for the most part this one was quite different from most Japanese monster films of its day. Just needed more monster action. Though one thing I notice a lot of people saying about this is that the people in the film seem to say that the appearance of the dinosaurs causes the volcano to erupt, but in actuality the scientist is saying that if there was a dinosaur present than the conditions are such to release it from its slumber and one of the conditions is that there is going to be an imminent eruption of Mount Fuji. However, for the most part the film has way to many plot holes and such and suffers from not enough monster action.
