It was made like a black & white movie (not totally
colourless though). The period was pre World War II era, but all
the machines and weapons were very high tech. One thing amazing
about this movie is: it was filmed in a studio with nothing on the
background, except a blue screen. There were only the actors and
actresses, and the rest were created by special effects.
Quite good. I give it 4 out of 5 stars
