1/4 of the film is stock footage from two earlier Gamera films
Daiei Film had finally figured out how to make a successful monster movie after three tries with Gamera. This was the fourth release in the franchise and it took a step backwards. It originally came out in Japan as Gamera vs Viras, but for the American audience it was called Destroy All Planets.<br /><br />Things start with an alien race wanting to colonize Earth only to have the big turtle run into them and destroy their ship. By this time Gamera had gone from a menace to humanity to its protector.<br /><br />Gamera had also always been a children’s movie. The first film for example featured a little kid that loved turtles and then came across Gamera. This one has a group of boy scouts as the main characters. The problem is the movie spends far more time on the kids than the monster.<br /><br />Another issue is it seems like the studio ran out of ideas with this film. Hence there’s a long sequence where the aliens want to find out Gamera’s weaknesses so they just replay the end fight from Gamera vs Barugon.. The fact that Barugon was a horrible looking monster doesn’t make this any better. Then they do the same thing with the third Gamera film Gamera vs Gyaos. There’s nothing that says lack of creative imagination then simply putting in a long scene from an old movie into a new one, and here they did it twice!<br /><br />Gamera was created in response to the Godzilla craze. It was never half as successful due to films like this one.
