Olsen and Johnson did four pictures for Universal, with diminishing returns each time. Hellzapoppin is an underrated masterpiece. Crazy House was fun but a big step down from Hellz. Then this one which feels like a pedestrian Abbott and Costello knock-off. They even reference that more successful Universal comedy duo in one of the film's meta jokes. Olsen and Johnson were basically a blend of A&C, Hope & Crosby, and the Marx Bros. I'm no film historian so I won't say who was first at any of the comedy devices employed by these teams. I do know who was best, at least onscreen, and it wasn't this pair. That being said, I have enjoyed their movies.
They aren't the biggest issue here anyway. The problem is the lame musical numbers. This is a common complaint today about many comedies from back then. The studios didn't seem to trust a comedy to sustain itself so they added romantic subplots and musical numbers. The best comedies rose above but this is not the best. The supporting characters are duds with some truly horrendous accents going on ("I'm a little sick of side pork and chitlins honey chile"). Lon Chaney Jr. Is wasted here in a throwaway goon role at a time he was the star of their monster films. The funniest scene in the movie involves "a horse." It's really not great but also not unwatchable. I feel like it's one of those movies I'm being too harsh on and after some repeat viewings I might feel better about it.
