Summary: “Fantastic Voyage” may not be as suspenseful as it once was, because we’ve seen many shots of the body’s interior and we no longer have the undercurrents of the Cold War that made life itself an edge-of-the-seat affair. But it’s still a fun sci-fi excursion.
Excerpt: Nevermind how many angels can dance on the head of a pin; how many soldiers can you fit on the flipside of a bottle cap? Quite a lot, as it turns out. The United States' military has devised a way to shrink anything -- tanks, planes, entire battalions -- to microscopic size, potentially redefining warfare as we know it. The technology to shrink things down is less complex than you might think, and some of our enemies have already mastered similar processes.
Summary: Fantastic Voyage may strike some younger viewers especially as being a bit on the quaint side, but in its day the film was a state of the art special effects wonderment and probably the single most influential science fiction outing of the sixties prior to Stanley Kubrick's immortal 2001: A Space Odyssey .
