Gambling Terror was one of the more worthwhile entries in Johnny Mack Brown's so-so western series for producer A.W. Hackel. The no-frills plotline finds hero Jeff (Brown), ostensibly a dude gambler, taking on a band of cowboy racketeers. The "big boss" turns out to be the outwardly respectable Bradley (Earl Dwire), a frontier Capone who runs a profitable protection racket aimed at the local cattlemen. The direction and camerawork are sloppy, but the action content can't be faulted. Appearing in support of Johnny Mack Brown are Iris Meredith and Dick Curtis, soon to become fixtures of Columbia's Charles Starrett westerns.
