Karloff and Lugosi are in fine form in this Universal picture, with the former essaying the not-unusual role of a scientist gone mad (here driven murderously so by exposure to the dreaded Radium X) and the latter a humanitarian doctor who saves the scientist’s life but must eventually face the consequence of his action. Well worth a look for fans of either.

  Recommended. Otto finds this one pleasing enough to relax.

Movie 541 for 2021.
