Reptilicus (Denmark)

What's Happening: Giant reptile attacks Copenhagen and spits green vomit
Famous For: Monster movie made in Denmark
Q: What's the silliest giant monster movie ever? A: Either The Giant Claw or Reptilicus. Most viewers will go with Reptilicus. Virtually nothing succeeds on its own terms, not the junior high-level plot and dialogue, not the obvious miniatures, not the thin characters, not the jerky puppet monster. Luckily, most of it is very funny. Crowd and army scenes are interspersed with the monster puppet, but we virtually never see them superimposed. Since the crowds and soldiers are real, and since the monster is so plainly fake, it feels like we are watching two different movies stuck together.

The monster resembles Toho's Manda, but it spits green vomit on its foes (some sources claim lightning bolts, but it's obviously vomit and referred to as "acid slime"). When the animated vomit lands on the soldiers, it simply fills the screen. The budget didn't even allow for fake green gunk to throw on people. In several crowd panic scenes, you can see people laughing (Toho also had this problem and had to re-shoot many such scenes). The co-heroes are a futtydud professor (as in Beast from 20,000 Fathoms), an annoying general, and an effete miner named Svend. Only the professor is likeable. He has two daughters who stand around and look cute.

Apparently, the monster flew in the European cut, but AIP deemed these sequences so unconvincing that they ordered them removed before distributing the picture in the States.
