Hammer Studios followed up Evil of Frankenstein with this entertaining sequel, again starring Peter Cushing as the quintessential mad scientist obsessed with the reanimation of dead bodies and the creation of superhuman creatures. His latest project involves transferring the mind of a wrongly-executed man into the body of his lover (former Playboy centerfold Susan Denberg), whose own suicide left her horribly disfigured. After restoring her beauty, the Doctor performs the mind-transference, which comes off without a hitch... until the lust for revenge against his executioners begins to surface. He/she then pursues this vendetta by seducing and murdering those who wronged him. Hammer stalwart Terence Fisher directs this quirky entry with his usual flair -- aided considerably by a decent budget -- and spices things up with a fair share of titillation (courtesy of Ms. Denberg).
