A scientist is nearly assassinated. In order to save him, a submarine is shrunken to microscopic size and injected into his blood stream with a small crew. Problems arise almost as soon as they enter the bloodstream. (IMDb)
The awesome opening credits here set the bar for cinematography a little too high for a film that mostly takes place in a human body portrayed by cheesy and underwhelming visuals. The story, meanwhile, loses the luster of its intriguing set-up from outside the bloodstream as it never really picks up the pace on the inside, with its points of crisis too far apart and often featuring dated special effects. The tense silence in the operating room when the sub is in the ear is a great moment though.
