Will make the science teachers cringe.
5 April 2005 | by (Mansfield, CT USA) – See all my reviews

"King Dinosaur" takes place on a new planet that has entered our solar system. Four astronauts are sent from Earth to explore it. The plot is about what happens to them during this exploration. The science that the kids saw while watching this movie must make science teachers cringe. Everything about this new planet is laughable and the explorers are a joke. It's just like being in the woods on Earth. The monsters are ordinary earth animals and insects. Some are enlarged, some have fins or other things put on them to change their appearance and some are just the way they look on Earth. Throw in some stock footage and you have "King Dinosaur". The astronauts are more on a camping trip than investigating a new planet. The two men are macho and the two women scream a lot. The so called special effects were bad in 1955 and are just laughable today. The main attraction to this movie is the humor you can find in it. The only entertainment value I found with this film was seeing how naive the characters were and how badly done the dinosaurs were. Oddly enough, it is bad enough to make it worth watching. It's good for laughs and to see what was around in the 50s. I wouldn't count on much more.
