Actual U.F.O.s were filmed, messing up some of the shots in the movie. Those takes were used anyway. The U.F.O. footage was uploaded to YouTube. Shown in the video titled, "UFOs, Ghosts, and the filming of Natzee Zombie Carnage".
The film's Director, played the German Major, an American Lieutenant, the British Commando Major, and 90% of the zombies. Fifty Three other people played parts in the movie. Some also filled in as a few of the zombies. Not all the zombies were people. Some were dummy puppets.
The American Lieutenant Smith, and British Commando Major Smith, were suppose to be related. As well as all the other American GIs that Nicholas B. Weed played. They were all related characters with the last name "Smith".
The German Major Necromancer charter was named "Major Alucard", Dracula spelled backwards. He was a Vampire Nazi Officer that used Black Magic to resurrect the dead, and blot the sun from the sky. The role was played by Nicholas B. Weed, and Flavio Erwin filled in as the stunt double. Besides being the "Day Walker" Nazi Necromancer version of Dracula, he was also the Devil. Or, at least possessed by the Devil. There was a Devil mask used in one of the dark ritual scenes. His' skeleton also had Devil horns. He was like, Dracula possessed by the Devil, as a Major in the SS.
The film's Director tried submitting the movie to 957 film festivals. A few actually showed the film at their events, but the majority simply rejected the movie. After a failed effort of trying to get the movie out there in the world by the use of film festivals, the director left the movie viewable on Film Freeway, and uploaded it to YouTube. Any hopes of ever making back the cost of production for filming, "Natzee Zombie Carnage", ended in bitter failure. The movie got made, but was a financial flop.
