Universal has brought all of its terror figures – Dracula, the Wolf-man and Frankenstein’s Monster – together in a nifty thriller for the chiller trade.
Plot twist has two of the monster heavies taking a sympathetic angle. Each comes to a doctor for help in curing their strange afflictions. First to appeal for help from Onslow Stevens is John Carradine, the centuries-old vampire. Next is Lon Chaney, the werewolf, who wants the doctor to relieve his madness. Stevens is successful in his experiments with Chaney but the vampire curing backfires. The good doctor eliminates Dracula by letting the sun’s rays fall on his sleeping body but finds he himself has acquired the blood-letting urge. In his newly-acquired madness he revives Frankenstein’s monster, found in sea caverns near the doctor’s castle.
Femme spots go to Martha O’Driscoll and Jane Adams as assistants to the doctor. Lionel Attwill is seen briefly as the village police chief, while Glenn Strange dons the garb of the monster.
