An interesting film that blends a Jekyll & Hyde type of theme with a Burke & Hare body stealing plot, and ties them together with a medical plot involving the discovery of anesthesia. Boris Karloff stars as a respected surgeon in Victorian London who is committed to finding a way to perform surgery without inflicting pain on his patients. He develops a gas mixture that seems to work, but finds nobody in the medical establishment willing to believe him. He experiments with the formula on himself, and through a mixture of overwork and increasing addiction to the narcotic gas, wanders around London at night with no memory of what happened. He falls in with a criminal gang at an unsavory pub that want to use him to get fake death certificates for the bodies they sell to the hospital. A really classy horror outing that features one of the only pairings of Karloff and Christopher Lee (as the body snatching, murderer Resurrection Joe).
