Although Hoppy wears a plaid shirt & a white hat (usually a sign of a lesser Hoppy movie, as opposed to his wearing an all black outfit), there's quite a bit to like in this film. It's filmed in the "High Sierras" per the credits, & redwood trees are seen (does anyone out there know if redwoods are indeed found in the High Sierras?). There are lots of good fight scenes with Hoppy & California as participants. Maybe the best part of the film is that Jimmy Rogers (my least favorite of Hoppy's young sidekicks) is sent on a mission to get Buck Peters, & thankfully is absent for 10+ minutes of film! Unusual for a Hopalong Cassidy movie, California is actually very helpful in three situations. William Boyd (apparently without stunt double) is active in fights, running, riding hard, & climbing down a fifty foot log wall (this with cuts, of course). The ending matches a standard serial thriller for excitement & lack of realism! Despite all these interesting aspects, the film falls short of a real good western, & lacks the good humor that Hoppy films were known for. I rate it 6/10.
