Did You Know?


Many of the invasion scenes in Tokyo were edited from World War III Breaks Out (1960). The appearance of a giant billboard of Adolf Hitler has led some viewers to believe that the stock footage is taken from documentary footage of World War II Japan. See more »

A tragic waste of the human spirit...
22 September 2002 | by (SOT) – See all my reviews

Wow! This movie (I use the term loosely) really, really sucked. Thankfully I saw it with Mike and the 'bots...and they could barely make it through this abortion. I could barely make it through. Waaaaaay too much stock footage, waaaaay to many annoying kids. What made "Prince of Space" at least mildly amusing was the phantom of Krankor. At least he had a personality. The neptune suppositories down even talk.
