The Rich Are Always With Us), but The Big Shakedown is not one of them. It's a rather ludicrous melodrama about gangsters making counterfeit pharmaceuticals, and the devastating effect this has on the absurdly naive pharmacist (Charles Farrell) who helps create the products.
Although there is some fun pre-Code nastiness here (the gangster gets his comeuppance by being dumped into a vat of acid), The Big Shakedown is resolutely square and dull, with a bland lead performance from Farrell. Davis has a few cheeky moments with the drugstore's goofy customers, but mostly she just has to stand around and look either concerned or proud. Glenda Farrell has a much sassier, Davis-like role as the gangster's moll, although it's a pretty small part. The movie barrels through its moronic plot in a little over an hour, and the actors just stand around and try not to get run over.
