Unknown Island is a low budget adventure-thriller in Cinecolor. The acting is creaky, and the prehistoric beasts look ridiculous. An engaged couple charter the ship of a salty captain to sail to a mysterious island rumored to have live dinosaurs. The man chartering the ship (Ted Osborne) says he only wants to take pictures of the beasts he once witnessed as he flew over the island in an airplane (we are then shown a hilarious "photograph" he took from the airplane of one of the dinosaurs), but we soon learn he is a selfish and slimy type of guy. His fiancee (Virginia Grey) is helping finance the expedition, and seems to want to only take a leisurely part in the trip. The salty captain of the ship (Barton MacLane) proves to be a masher to the lady, and a selfish jerk as he decides he wants one of the beasts to take back for the profit. His decision leaves everyone on the island longer, and in constant threat of danger from the wild, prehistoric beasts. Richard Denning has also once witnessed the horrible beasts of the island, and he plays an alcoholic who learns to sober up during the return to the island. A mutual interest becomes established between his character and the woman. Upon nearing the island we get to witness a brontosaurus pair, which are badly animated stop-motion models. The cast is "menaced" on the island by ridiculous carnivorous dinosaurs that make hilarious vocal noises, and by a sloth creature which is a man in a sloth suit (LOL.) There's even a rubber dimetrodon creeping around the island. The salty captain's workers don't always appear to be the ethnic types they're supposed to be, which is funny as a flub in the film. I will say the jungle setting does look nice, and the Cinecolor is interesting. Bad special effects, flubs, and a general ridiculousness make this movie somewhat laughable and fun to watch.
