This movie has everything in it! A group of balloonists are shipwrecked on a desert island after a storm and encounter an Amazonian tribe, who are descended from space aliens, crazy looking ping-pong eyed zombies and the grand-daughter of Dr. Frankenstein, who is still doing experiments. It seems that whoever is shipwrecked on the island is experimented upon, such as a previous group of sailors. The ghost of Dr. Frankenstein, provided by one minute of footage of John Carradine, keeps on making appearances, uttering the same lines over and over again (probably all they shot!), which makes it all the more surreal. Cameron Mitchell and Robert Clarke are also on hand to emote. A really weird but entertaining movie.
