before i hang represent negative represent boris karloff star a dr. kevorkian in this expose of stem cell research go wrong . okay maybe that be not completely accurate but one might certainly think along those line a a doctor find guilty of a mercy killing be sentence to hang despite his promise youth serum . karloff quickly find himself in a prison experiment with the blood of a recently hang killer the clock tick against his own execution . he inject himself with the serum it work the governor pardon him and he go off to save the world . actually that be not completely accurate a well . apparently the blood come from the prisoner abby normal and karloff start get that look in his eye and his over sized handkerchief out of his pocket and the population of the movie start drop precipitously . the movie be poorly direct and despite some initially good albeit rush idea it quickly fall into the old blood memory turn man into killer nonsense . the pacing be bizarre with a ton of plot simply explain through voice over ( the hanging verdict in particular seem unlikely a show ) in the first half the second half with karloff stalk the elderly drag . a weak film that start of strong and quickly go nowhere .
