This starts out so well. We have a man who really shouldn't have been executed, facing the music for doing an act of kindness toward a fellow human being. The people around him give him his wish to continue to do research and he is eventually pardoned because of his great discoveries. Unfortunately, to prove his point, he gets injected with the blood of a three-time killer who was hanged. Of course, true to plot, Karloff's kindly old doctor begins to black out and do evil deeds to the people he loved. He has discovered a sort of fountain of youth, but his old buddies realize that he is messing where he shouldn't have been messing, and want nothing to do with it. Whenever he gets all worked up, he becomes a strangler. There's nothing very remarkable about it and the science is quite ludicrous. Karloff and the rest of the cast give it the old college try, but the thing is so lame that it just falls flat. Totally predictable.
