Karloff often portrayed characters who were torn between good and evil - memorably in THE BLACK ROOM where he played twins, but I have never seen him do such a great job of acting as he does in this film.
It opens with him portraying an old, weak, good intentioned doctor - a sympathetic and at times pathetic character. But once he injects himself with a serum that was made from tainted blood, that of a serial murder, he changes. He is younger in appearance and action, and he is a killer, a tortured one, but a chilling one as well. It's great to watch.
While the movie has the weakness of being a cheaper B-film, there is still a lot of good work in it. The camera work with the use of light and shadow is exceptional, the music is better than in some other Karloff films I've watched, and the scenes involving blood are almost too strong to watch.
Often in these films there are times when you think they could have been much better with a bigger budget, but they still accomplish so much. The scene where the doctor's daughter goes into his lab and the door closes behind her, shutting us out for just a moment, gave me a chill as good as something from Alfred Hitchcock's FRENZY.
So catch this little known gem and enjoy it.
