7. The Angry Red Planet (1959)
This is almost cheating as there are three key monsters in Angry Red Planet which was filmed in Cinemagic at the request of producer Norman Maurer; an early attempt at using hand drawn backgrounds into live action Special effects were created by Bob Baker who has an uncredited role in Close Encounters of the Third Kind (also no relation to the infamous Rick Baker) and Herman E. Townsley (House on Haunted Hill). Angry Red Planet is definitely a hostile planet as one of the crew is attacked by a giant carnivorous plant. The plant creature itself was well done and if the movie had more of them (director Ib Melchior only had ten days to shoot the entire film) littering the whole planet, it could have made the whole situation far more threatening and entertaining. The same could be said for the giant amoeba creature with its one giant eye when it attacks the crew in their inflatable raft. Last we have the bat, crab, spider-rat thing. Surely something Dr. Moreau would have come up with in his lab. Towering at 40 feet in height, this roughly 15inch marionette was the work of Bob Baker and his marionettes. It is also the most ridiculous creature ever created but that is what makes it fantastic.
