Bar 20 Justice is the 16th entry in the durable "Hopalong Cassidy" western series. As ever,
William Boyd stars as Hoppy, this time teamed with Windy Halliday (Gabby Hayes) and Lucky Jenkins (
Russell Hayden). On this occasion, our heroes take on a bunch of crooks who've taken over a mining concern. In order to capture the criminal responsible for murdering the husband of heroine Ann Dennis (Gwen Gaze), Hoppy is obliged to head deep, deep, deep into a forbidding mineshaft. The excitement level of the closing scenes is enhanced by an intricate musical score. The bad-guy lineup on this occasion includes the swarthy
Walter Long and the outwardly respectable
Pat O'Brien. Bar 20 Justice was directed by
Lesley Selander, who would eventually helm 27 of the 66 "Cassidy" films. ~ Hal Erickson, All Movie Guide
