A rousing good time for Abbott and Costello fans is contained in this spoof on fiction’s classic bogeyman [from stories by Sidney Fields and Grant Garrett]. The fat & thin comics combat Boris Karloff as the fictional dual personality in the very broad doings, and Karloff’s takeoff on the character adds to the chuckles dished out by A & C.
Helen Westcott, ward of, and coveted by, the good Dr. Jekyll, supplies excellent femme appeal in a romance with Craig Stevens, a reporter, while Reginald Denny, harassed Scotland Yard inspector, and John Dierkes, the doctor’s zombie-like assistant, help the fun.
Bounced off Denny’s police force because of their bungling, Abbott & Costello figure they might be able to get their jobs back if they catch the monster that is terrorizing Hyde Park. Comedic chills and thrills ensue as the pair track down the monster and wind up with its alter ego, Dr. Jekyll.
