Larry and Mary, young stars of high society, eye each other from their respective boxes at the race track. Mary's aunt warns her that Larry is "notorious"; Mary coolly replies that he's awfully good looking. Larry rides his own horse in the steeplechase—and is thrown off. Faking injury, he catches a ride to the hospital with his head on Mary's shoulder…and the two are quickly engaged. From there the plot takes a while to develop, but eventually….Larry is (mistakenly) convicted of killing a gambling hall owner, escapes from the train on the way to prison, and somehow makes his way to….Monte Carlo! where he suspects the real killer has fled. In Monte Carlo, he befriends a young French woman who becomes devoted to him, and pursues his only clue: the killer always plays numbers 7, 14, 28 and 29 on the roulette table.John Darrow and Mary Brian do well as Larry and Mary; both develop interesting and distinctive characters that viewers can root for. To the newspapers, Mary is "Little Mary of the Vernon Millions," but she quickly establishes an independent streak that worries her protective aunt. Larry has "a reputation" but he's charming and dashing and—it turns out—tough and resourceful.George Hayes plays the other major character, a police detective named Gunby—yes, a detective in a coat and tie. He watches with narrowed eyes, asks questions and adds up details, concludes that Larry is indeed innocent…and also sets out for Monte Carlo to hunt for the real killer.Astrid Allwyn is excellent as a dangerous blonde who tries to pull a fast one on Larry and Gunby. An actress named Yola d'Avril is sad but loyal as Larry's Monte Carlo assistant. There's no shortage of plot in this 62-minute adventure. And it keeps the viewer guessing—the suspense is not exactly unbearable, but it does build nicely to a well done climactic scene. Fans of Monogram's 1930s westerns will enjoy not only George Hayes but a quick glimpse of the great Yakima Canutt phoning the police—in a tuxedo!

I searched for this film for one reason only: I really liked Mary Brian in the W. C. Fields film "The Man On The Flying Trapeze", and wanted to see more of her. She is sweet and beautiful but a little bland in this film; in fact, I would say that two other actresses, Yola d'Avril as a French girl who loves the hero but is not loved back and Astrid Allwyn as the killer's girlfriend, make more of an impression. Although it is made by Monogram studios, which have a reputation for cheapness, "Monte Carlo Nights" has higher-than-expected production values, including a horse steeplechase and a daring jump from a moving train. But the story is unlikely, short on mystery, and not very engaging. This is not a bad movie, but if you miss it, you won't be missing much. ** out of 4.

This movie is not that bad, a decent time waster if you don't mind watching old black and white movies. I think most of the negative comments are coming from people who just don't like old black and white movies or they are expecting them all to be as good as Hitchcock, to that reviewer I say you are right it's not as good as any Hitchcock film but it is still a decent enough way to spend a couple hours.It's a mystery film noir type movie where the main character is accused of murder but escapes and strives to hunt down the real killer on his own to get revenge but also obviously to prove that he is innocent of the crime he has been accused of. The actor playing the main character gives a good performance and so does the actress in the main female role.

A man found guilty of a murder he didn't commit, a daring escape by leaping off a train crossing a bridge, a shooting in a café and a scrap of paper that leads to a denouement in Monte Carlo --- these are the plot points that tell you you're watching a great Hitchcockian thriller. Only it isn't a Hitchcock picture, it's directed by William Nigh for Monogram and it is pretty poor -- especially as we've seen Hitchcock do it right, starting a year later with THE 39 STEPS. Really, the main reason to see this movie is to serve as counterpoint to Hitchcock.Even the sound system seems off. Everyone speaks their lines with great emphasis as if every article is of great importance. There are some good actors lurking here, including gorgeous Mary Bryan, Astrid Allwyn and George 'Gabby' Hayes, clean-shaven, hair neatly combed and his teeth in. But really, you'd do yourself a favor by giving this one a miss.
