Film: King Dinosaur (1955)
Alias: Planet Nova Inbahibants (including Giant Jerusalem Cricket, Giant Monitor Lizard, Giant Caiman, Giant Armadillo, Giant Mastodon)
Height/Weight: Varies from the size of cars to that of small buildings.
Summary: When you're out of ideas, just hit the pet store and BOOM! You have a fine cast of monsters to populate your own B-movie! Now keep in mind that most of them must be reptiles for added gravitas, and they should want to kill each other very badly. After all, if those One Million BC folks could do it, so can you! And while we're at it, take some stock footage from them as well. They don't mind.
History: In a flash of cosmic power, a new planet has been formed, and humanity has taken notice. This planet, known as Nova, was visited by a group of intrepid explorers searching for potential colonization. The atmosphere was perfect and the environment wasn't too far off from our own, but there was one key difference. Almost all the planet's top predators were super-sized versions of Earth's insects and reptiles. And at the top of the pecking order was King Dinosaur, a massive Tyrannosaurus Rex whose very visage commanded-oh, who are we kidding? It's a big green iguana with a horn attached to it. Doesn't make it any less dangerous, though.
Notable Kills: See Final Fate.
Final Fate: The cricket is gunned down, the caiman and monitor lizard are reduced to bloody corpses by King Dinosaur, and the humans manage to nuke the island that the big iguana was on. Why a nuke? Because America, that's why.
Powers/Abilities: Nothing special except sheer size.
Weakness: Anything conventional.
Scariness Factor: 3-King Dinosaur can be a little unsettling at times, and the fight scenes are impressive at times, but aside from that, they don't do much, and the cricket looks pretty bad in terms of super-imposing.
Trivia: -This film was the directorial debut of Bert I. Gordon, or as we know him here, the B.I.G guy.
-This film was also shot in exactly seven days.
