I'm not sure if I've seen a Ritz Brothers movie before this one. In terms of brother comedy acts they haven't stood the test of time like the Marx Brothers, perhaps because they lack distinctive personalities, but they have a lot of energy and know how to sell a joke.
The rest of the cast is fine. Ethel Merman is the standout of the bunch, but her character is little more than a character device devoted to either breaking the obligatory cute couple up or getting them back together. She has a couple of good songs, but seems to good to be a bit player in a low-budget comedy.
The film's biggest weakness is the script, which is just a mess. It centers around a relationship in peril because of the woman's love of her horse, and it can be remarkably inane. Besides Merman's poorly-defined character, there is a "bet" that makes no sense and a moment when the guy, who is portrayed as being a really swell fellow, considers doing something not-good to his girl's pet. The lack of character continuity is so notable that it feels like the characters were written by several different writers who didn't read any part of the script they didn't write.
But it's quite amusing all the same.
