If you're a fan of random stock footage of animals from the early 20th Century, this is the movie for you. At least half of the film is taken up with clips of animals that are so poorly shot, it's often difficult to see what you're looking at. Animals that in nature are continents apart are presented as if they live in the same African jungle. I swear that some of the animals even appear to be in zoos or other unnatural settings. Piece these clips together, throw in a nonsensical story about the search for a lost city by some bored rich dudes, and add an even more nonsensical plot line where Buster Crabbe is searching for a cure to a deadly disease by slaving over a Bunsen burner in the jungle - you've got Jungle Man. By the time our heroes come down with the illness, I had long ceased to care about any of it. I was rooting for their deaths as it might mean the movie would end faster. It's all a total bore. The one hour run-time feels more like an eternity. If you can't tell, I didn't care much for Jungle Man.
The lone highlight for me was seeing Buster Crabbe and Charles Middleton together on screen. I'm not much a fan of the old Flash Gordon serial, but I realize it's historical significance. Seeing Flash and Ming together here was pretty cool.
