1941's "The Strange Case of Doctor Rx" was part of Universal's popular SHOCK! package of classic horror films issued to television in the late 50s, turning up twice on Pittsburgh's Chiller Theater, on May 8 1976 (following Cameron Mitchell's "Nightmare in Wax") and Jan 29 1983 (solo). Yes, Lionel Atwill is criminally wasted, but what's worse is how the ads promoted it as a horror film prominently featuring his countenance (billed second, as he also was in "The Mad Doctor of Market Street"). Patric Knowles is the actual star, before "The Wolf Man" and "Mystery of Marie Roget," and has no trouble carrying the picture, but the on again-off again sparring between his detective Jerry Church and new bride Kit (Anne Gwynne) wears thin very quickly. Church has just returned from South America, only to be bludgeoned by the recent series of murders committed by a mysterious Doctor Rx (not to be confused with Atwill's 1932 "Doctor X"), who executes criminals that escape the justice system. The couple are likable performers, but the 'Battling Churches' were mercifully not granted a sequel (it really is less a horror film than a domestic mystery/whodunit, certainly no THIN MAN). Still entertaining for those who encountered it long ago, particularly for the excellent cast, with Samuel S. Hinds, Paul Cavanagh, Mary Gordon, pretty Jan Wiley, and Ray 'Crash' Corrigan as the gorilla Nbongo, in the lone nightmarish sequence that climaxes the picture. The underrated Mantan Moreland, who always rose above his material, easily steals every scene he's in, which the better known Shemp Howard fails to do (some 5 years before he rejoined The Three Stooges).

"The Strange Case of Doctor Rx" is billed as a horror film, but it really isn't. It's an all too obvious murder mystery with just one horrific scene that seems spliced in from another movie altogether. William Nigh probably relished the chance to direct at a major studio instead of the salt mine of Monogram, but though the film has handsome production values Nigh brings to it all the trademarks of his Monogram work: dullness, no sense of pace and an unwillingness to tell any of the actors they're overacting. Though billed second, Lionel Atwill is barely in the movie at all until the final reel. The title is obviously intended to evoke memories of Atwill's great film "Doctor X" from Warners in 1932, but the comparison only makes this film seem even worse than it is. The great Black comedian Mantan Moreland easily steals the movie out from under all the white stars; he's genuinely witty and a charismatic screen presence, and he gets the first line of dialogue as well as the final gag. Next to Moreland, the most entertaining aspect of the movie is Patric Knowles' gorgeous Art Deco apartment, where all too much of the film takes place. Why Universal and TCM chose this for their "Cult Horror Classics" boxed set instead of the neglected 1934 masterpiece "The Man Who Reclaimed His Head" (also with Atwill) or the interesting 1942 Edgar Allan Poe adaptation "The Mystery of Marie Roget" (also with Knowles) is a bigger mystery than the supposedly "mysterious" identity of Dr. Rx in this plot.

Easily the worst Universal "horror film" I've ever seen, and it makes previous candidates of mine like SHE-WOLF OF London, THE FROZEN GHOST, and JUNGLE WOMAN look like thrill rides alongside it. Hell, I'd even watch LIFE RETURNS again over this one; at least that's bizarre enough in its badness and resembles an Our Gang short in spots. DOCTOR Rx doesn't make one bit of sense, with nothing going on but talk, talk, talk, and feels like it goes on forever despite that it's only just over an hour. The cockeyed plot seems to be about a series of murders against criminals who got off, committed by a mysterious doctor. Shemp Howard and Mantan Moreland are mixed up in all of this, but they don't even offer anything fun in the comical department. Anne Gwynne had always been the cutest Universal gal for me, but despite all her pep here it's all for naught. And Lionel Atwill is just wasted. The only somewhat decent thing I can say for this turkey is that it was semi-interesting to see Patric Knowles cast as an insensitive jerk for a change, and the 3 measly minutes we spend in Dr. Rx's laboratory with a chained gorilla is a tad unsettling ... even though I can't for the life of me see how it fits into the rest of this picture! A wretched movie. * out of ****

(possible spoilers) If you're looking for a lot of Lionel Atwill, you will be disappointed as he only has a few scenes playing the most obviously named red-herring in film history, Dr. Fish. However, if you're looking for a good little suspenser, this is a solid b-movie from Universal. The cast is generally good, only Patrick Knowles comes off as too brash and pompous as the hero. It's hard to root for him as his charm is very thin and his arrogance fat. It is nicely paced and directed. The best part about the film is Dr. Rx himself - a madman vigilante killer with an evilly raspy voice and a gorilla for a sidekick. It's a fun time-passer and one of the better horror/mysteries from Universal.
