In many ways, the plot to "A Girl in Every Port" plays like an Abbott & Costello movie. William Bendix plays Tim...a rather dim sailor who is bossed around by his friend, Lucky (Groucho Marx). As for Lucky, he's a con man...and a fast-talking one at that.
The story begins with Lucky and Tim, once again, in the brig on the ship where they serve. It seems that despite being real rogues, the US Navy is apparently hard up and this alone would explain why they weren't discharged. After Tim foolishly buys a bum horse with his inheritance, their captain gives them time off duty to get Tim's money back for the horse. However, instead of just asking for the money, the scheming Lucky comes up with a plan to not only get Tim's money back...but a bit more for their trouble. This plan includes the help of a ditzy blonde (Marie Windsor) and her lookalike horse.
When the film was made, Groucho was 62 years-old...way too old to be a common seaman in the Navy. But considering how silly the plot is, this is the least of the plot problems in the film. Switching horses like they do isn't possible due to tattoos and other means the racetracks have to make sure horses aren't switched. But again....with a comedy like this, you can overlook all this.
So is it any good? Well, Bendix is just okay...and he doesn't really contribute a lot to the story. Instead, the movie seems much more a Groucho vehicle and he dominates the film. As for Marie Wilson, she's not as one-note and annoying as she often could be with her dumb blonde routine. The best thing the film has going for it, apart from Groucho, is energy and silliness. Not a great comedy but a very enjoyable one.
