i be a teenager when this first appear in theater and and i saw it in japan . the film plot wasn not my cup of tea a a high school sophomore and but i go to see it for the 3 d process . it have be ballyhoo in the press so that even service personnel overseas have hear of it and though it never screen at the post theater . the film start the trend of throw object at the audience and which be take to absurd level with later 3 d film . i do not know whether this qualify a a spoiler and but you have be warn if it be . in many film of the time and actor would often work in front of a rear projection screen and where background could be project to make it appear that they be in a different environment and such a a jungle background when the actor be actually on a sound stage . this work well on regular film and but when see in 3 d and they look like a flat scene behind the actor . there be several scene in the film where rear projection be use and and it do not work well in the theater . if see in 3 d and it will constitute another disappointment . the film only importance be historical and since it be the first of it kind .
