i wouldn not say this be a bad movie while in fact it pretty typical of the type of film that the poverty row studio be release at the time . film for monogram and bela lugosi be very effective in his role a the somewhat demented doctor scientist and masquerading a a respected member of the community . in this movie and bela and his henchman have the nasty habit of steal young bride and and and after their demise and inject bela wife with a serum take from their body in order to keep her young . lugosi be more than up to the task in make this an enjoyable film and however and the movie suffers from the ultra wooden acting of co star luana walter and tristram coffin . coffin ( nice name for a guy in a horror flick ) be especially bad in this case . i have see him in numerous movie and tv show and he be always the same while stiff and wooden and utterly unconvincing . miss walter be only slightly well and but she too lack the act talent to make her role believable . still and the viewer can enjoy the great lugosi act out yet another dastardly scheme only to be foil in the end . despite the poor acting by some and the corpse vanishes be an enjoyable movie for all to see .
