Bogart has been given a bad press for his role in "The Return of Doctor X." Why he even gave himself a bad press, saying the role was forced on him by the studio, a role intended for Boris Karloff. But actually Bogart's performance is one of the best ingredients in this campy flick. Bogart's two really terrible acting attempts were the same year in "The Oklahoma Kid," where he tried to play dastardly villain, Whip McCord, and "Dark Victory," where Bogart is completely miscast as an Irish horse trainer.
Nineteen thirty nine must have been Bogart's quirky year. He finally found himself in the early 1940's and with "The Maltese Falcon" became a screen icon. In "The Return of Doctor X," with his chalky makeup and streaked hair, Bogart resembles a punk rocker before his time.
The film is not bad entertainment. The weakest part is the attempt by Wayne Morris to be funny. He thinks falling into a room by leaning against a supposedly locked door which suddenly opens is hilarious. So much so that he does it twice. The funniest character is Huntz Hall early in his career. There is one funny line from Morris. After digging up Quesne's body and in a hurry to leave, morris tells the caretaker to "put it back," then rushes off.
The acting is top notch with the best performance coming from John Litel, closely matched by Bogart's left-field mad dead doctor. All in all a curious and worthwhile film, especially for Bogart fans.
