Texas Masquerade (1943) is not a frontier Halloween party, but Hopalong Cassidy (William Boyd) and California (Andy Clyde) give some two-fisted "treats" to a gang of masked riders out to "trick" local ranchers out of their land. Then, "The Marauders" (1947) finds the black-hatted hero settling a score with a band of murderous owlhoots who've driven a whole frontier town out so they can dig for oil. "The Border Vigilantes" (1941) are hired to help a mining town save its silver from being hijacked by some blackhats, but it's up to Hoppy to uncover the connection between the two groups. Clyde, Russell Hayden, Victor Jory also star. Boyd made his final screen appearance as Hopalong Cassidy in "Strange Gamble" (1948), which finds him hot on the trail of a counterfeiting ring in Silver City. With Clyde, Rand Brooks. "Twilight on the Trail" (1941) is more like "Tea Time on the Trail," when Cassidy poses as an English detective to find out who's been rustling cattle from his rancher pals. 5 hrs. total.
