When Hoppy dresses in his all-black outfit, you know there's going to be action & old fashioned western excitement. When Hoppy dresses in his tan or "dude" outfits, you know that William Boyd will get a chance to do more "acting," which he loved to do to break the monotony of his 66 picture run as Hoppy, but you can also expect less action & more talk. So one of the first things I look at, to foretell the type of movie it will be, is the clothes he wears! In this one, he starts out in black & then dresses as a dude in a white hat & sports jacket to go undercover. And sure enough, it's a so-so entry in the Hoppy series, not bad, but not great either. Gabby Hayes has a good role in this one. Worst scene: Russell Hayden (as "Lucky") plays guitar with the guitar invisible to the camera, while his romantic interest sings a western song in the finest pop-operetta style! Best scene: close-up of Boyd riding Topper at high speed. Hoppy changes back to black just in time to ride off with his friends as the movie closes. I rate this one 6/10.
