Other mistake: The Japanese plane and the German plane are actually the same aircraft type, a British Design called an "Eardly Billing." The "Japanese" version is re-dressed with canvas partitions between the wings, painted dragons, etc, the "German" has no canvas and German eagles, but they are the same machine.
Other mistake: Toward the end, Genius and Wolf (the dog) are in the lab, Genius suddenly shouts at the dog, "Hey, don't do that. Keep away." The dog wasn't doing anything except wiggle his ears a little. He made no move whatsoever toward the glass jar Genius wants him to stay away from.
Other mistake: This film was retitled for video, but whoever was responsible made an error. It was retitled Attack Of The The Eye Creatures with 'The' written twice in the title.
Other mistake: FBI Agent Kelso believes a cat may be able to lead him to the location of a kidnapped bank teller. He has four other men trying to follow the cat. When Agent Cahill reports that he is stationed "west of Whittier Street," Kelso sticks an identifying pin on a large map but he puts the pin in a location east of Whittier Street.
