Dr Jekyll & Mr Hyde is Robert Louis Stevenson's classic tale of horror, the duality of mankind and the darker side of late Victorian society. Dr Henry Jekyll (John Hannah), a great scientist, handsome, and renowned throughout the scientific community, is developing a formula that will revolutionise human nature by isolating criminal elements. He experiments on himself and intoxicated by the drug he undergoes a monstrous transformation. He is released from conventions of the social order and his own moral code into euphoric, remorseless wickedness - the villainous Mr Hyde. What follows is the gripping and terrifying stuggle of two opposing personalities battling for the soul of one man.
