Boris Karloff would begin to repeat what might be considered the same part again and again in a series of "Mad Doctor" films he made for Columbia Pictures in the early '40s. As the elderly Dr. Garth, Boris is developing a serum which he hopes may preserve life. He's been convicted of the mercy killing of a terminally sick friend (would that make Karloff the first Dr. Jack Kevorkian?) but yet is allowed to continue his experiments while on death row with the aid of prison physician Dr. Miller (DRACULA's Edward Van Sloan). Garth decides to use himself as a guinea pig and injects himself with a serum made with the blood of a known murderer. The kindly doctor is subsequently pardoned from his crime, and the end result of his experiment produces the amazing effect of turning him into a much younger man. He has now inadvertently reversed the aging process, but the tainted formula has one slight side effect: it periodically turns him into a homicidal killer who is seized with the urge to strangle his victims. BEFORE I HANG is a decent offering in this series, though is not to be confused with the similarly-titled and superior THE MAN THEY COULD NOT HANG from 1939. **1/2 out of ****
