From slashfilm [excerpt], The original film was released in 1966 and featured a Soviet scientist who discovers the key to miniaturizing things without danger of them reverting to their original size after a period of time. But an assassination attempt leaves him in a coma with a blood clot engangering his brain. A US team is miniaturized and sent into his bloodstream to destroy the clot and save his life. But they’re relying upon outmoded technology, and only have an hour to work before they begin to revert to original size, and are targeted by his immune system.
(As a kid, I always wanted to see the short version where the ship just instantly reverts to full size, exploding outward from the guy’s body.)
Because Cameron is reportedly producing this film, that leaves the gates open for speculation about his next directorial effort. It could still be the long-gestating Battle Angel, oceanic drama The Dive, or a segment for Heavy Metal, for which he’s been said to be a contributor. Or it could be something else entirely.
