This movie was different from most of Jimmy Cangey's films of the 1930s in that it was NOT done by Warner Brothers/First National, but was a loan-out to a smaller studio. Because it was a "poverty row" studio, the production values are lower than you might be used to seeing with Cagney films. Plus, the plot is certainly one of the strangest I have seen. Instead of him being a gangster, he was a good guy in this one--fighting for the law. This isn't all that unusual because Cagney frequently played lawmen--such as an OSS leader (the forefather of the CIA) of FBI agent. BUT, to make him an investigator for the Bureau of Weights and Measures was indeed odd--especially since, at times, he acted pretty much the same way he did in the movie G-MEN!
All in all, a time passer and that's about it.
Finally, the videotape I saw this on from Memory Lane Video was perhaps one of the poorest I have ever encountered. The sound was terrible and scratchy and the print looked very white and had lots of torn film and gaps.
