One of the reasons I like this movie is that Bob Kinoshita was the art director for it. Bob, of course, was the man who later did a great deal of work for both Forbidden Planet, and Lost in Space. The Earth space ships were actually pretty realistic for the time period, and some of the alien's technology seemed pretty cool to look at. For some reason, whenever I watch this flick, and they get to the scenes of the "dog faced aliens" attacking in their ships, I think of the TIE fighters in the original Star Wars (ep IV) Seems to me Lucas used that same sort of medium shot of the pilots in his direction... but, maybe I'm just seeing things.
