An incredible journey through the inner workings of the human body is now even more spectacular in Blu-ray high definition. In this Academy Award®-winning sci-fi adventure* starring Stephen Boyd, Donald Pleasence and Raquel Welch, an elite medical team in their state-of-the-art submarine, the Proteus, is shrunk down to microscopic size and injected into the bloodstream of an ailing scientist to save his life. Battling the body’s powerful natural defences--as well as a saboteur in their midst--the crew is in a race against time to complete their mission before the miniaturisation wears off.
