Hard to imagine selling this movie to a bunch of Hollywood film executives. No idea why they called it "...at the center of the earth," as it cheapens the movie and, in no way takes place at the center of the earth. Lots of "lost" history here, including the "hollow earth" theory, NAZI bases in Antarctica, NAZI UFOs, etc.
Very uneven production values. The gore is very realistic; however, the cyborg is unbelievably bad in some scenes. Continuity in some of the action scenes is also pretty bad, particularly with the cyborg. The nudity, albeit brief, is pretty gratuitous and the abortion without anesthesia and the "zombie-like" rape is downright distasteful.
Sound and photography are excellent. If you can handle the more gamy elements of the movie, you should give it a watch. I give "NAZIs at the Center of the Earth" a weak "6".
