I just wanted to make a comment about the quality of the singing. While Frank McHugh is always fun to watch, no matter what part he's playing, I kept wondering who was really singing during the operatic performances in the film. I think this page has a listing for the singer dubbing Carillo's part, but not certain about the rest. Anyway, the singing is top notch -- beautiful voices of Metropolitan Opera quality. Sad that this is not appreciated! Carillo was also pretty (deliberately) hilarious in his part, and I enjoyed watching him. Interesting that Duncan Renaldo (a very attractive young tenor in the film) teamed up with Carillo to play Cisco and Pancho in The Cisco Kid later on. This may be classed as a "B" film but there is a great deal of talent here, and Hollywood quality touches (like the truly good singing talent).

...and annoying is the best way to describe tenor and opera singer Gino D'Acosta (Leo Carrillo). In the looks department he is a solid 5/10 yet in spite of that and his obvious lack of sincerity and subtlety he is a lady's man with two currently on a string, he has an understudy that badly wants his big chance, then there are the boyfriends (husbands??) of the girls he is stringing along, and a lunatic that wants to kill D'Acosta because he won't sing an opera he has written. So when D'Acosta dies on stage it is no surprise to the audience. On hand to solve the murder is the reason I - and maybe most people - hang around. That reason is Chester Morris as Detective Steve Farrell. He teams up with Dr. Adams' niece Toni (Madge Evans) who is a chemist and helps him analyze evidence. You see, at first it is thought D'Acosta was poisoned by some wine he drank before going onstage, but the autopsy proves that the poison was delivered while he was performing, and now it is a combination of Steve's detective work and Toni's forensic analysis that work to crack the case. Madge Evans is playing this role somewhat as a screwball comedienne Jean Arthur style, and the result is a good performance and good chemistry between herself and the always entertaining Chester Morris who plays this role as a good yet tough guy.So what's not so good about this film? Mainly the short running time combined with, IMHO, an excess of opera music. The time taken up by the opera music could have been used to beef up the plot a bit more. Still I'd recommend it for fans of B murder mysteries from the 30's and 40's and definitely for fans of Chester Morris.

1936's "Moonlight Murder" may be from MGM, but its 'B' status is assured by starring Chester Morris, whose 'A' status had passed, but his solid pedigree remained for second features such as RKO's "Five Came Back," plus all 14 features in Columbia's 'Boston Blackie' series. Leo Carrillo is cast against type as opera crooner/lothario Gino D'Acosta, who has more than a few interested females, an escaped maniac (J. Carrol Naish) determined to do away with him, and a mysterious swami (Pedro de Cordoba) predicting his imminent demise if he performs his next opera. There's plenty of opera, predating "Charlie Chan at the Opera" by at least five months, and it does tend to slow things to a crawl, particularly after the murder, when we're itching for some mystery relief to take charge. Another commentator took note of the method of murder popping up in a 'Mr. Wong' feature, but there also were two Monogram Charlie Chans, plus Universal's 1939 "The House of Fear" as well. Director Edwin L. Marin never seemed to escape the 'B' tag (even at MGM), his best remembered features including his debut "The Death Kiss," "A Study in Scarlet," "Bombay Mail," "The Crosby Case," "The Casino Murder Case," "The Garden Murder Case," "A Christmas Carol," "Invisible Agent," "Tall in the Saddle," and "Nocturne."

Before a rehearsal at the Hollywood bowl, philandering tenor is warned of danger if he sings in the next nights opera by a mystic, The tenor laughs it off. When he's attacked by an escaped maniac everyone thinks that perhaps there is something to it. As show time draws near signs of danger increases until the tenor is killed during a performance in front of 20,000 witnesses. Things get complicated as more mayhem happens. Breezy murder mystery with Chester Morris and Leo Carrillo is the sort of thing that you might as well just sit and enjoy since odds are you're not going to figure it out (The clues are a late in the game revelation-revealed semi fairly). It's a got a great cast some good laughs (of the right sort) and a nicely complicated plot. If there is any real flaw its that there is a too much music. There isn't anything wrong with the opera scenes by themselves, rather its that this film barely runs over an hour and the lengthy singing scenes make the rest of the film feel rushed. Worth a look if you run across it.
