Buster Crabbe had the look, build, and voice for a western hero. Al St. John had the look, build, and mannerisms of the perfect sidekick. Gangster's Den had these two men as an advantage from the start, but the movie centers around the sidekick more than the hero. I'm beginning to notice that pattern to the Billy Carson series. In this movie Fuzzy ends up buying a saloon and all the trouble that comes along with it. I. Stanford Jolley plays a lawyer trying to illegally take control of a ranch and Fuzzy's saloon because a mine runs underneath. Half of the movie is over before the hero does anything heroic to catch the evil lawyer and his henchmen. Yes, Billy Carson looks good saving the day, but it's Fuzzy who has the fist fight with the villain in the end. There is no mistake that half of the screen time was given to Al St. John. He was good enough to carry a movie on his own.
Gangster's Den shows Charles King in an unusual role. He provides part of the comedy in this movie. Of all the movie bad men, Charles King was probably the best of the bad guys in the B western era. This time he plays an unruly customer in Fuzzy's saloon who gets hired to be Fuzzy's bodyguard.
King's character is hilarious as he mistakes getting hit on the head for the strong drinks he keeps ordering, and when he takes the job of bodyguard too seriously.
Emmett Lynn is almost a sub-sidekick to Fuzzy. The two of them argue with each other constantly in a way that only old sidekicks can. Kermit Maynard still looks strong and tough in this movie, and he has a better role in the movie than in so many other movies where he hardly spoke at all.
