There is a rather incongruous moment 20 minutes or so into Rough Riders' Roundup where a jailed Roy Rogers serenades cell-mate Mary Hart (aka Lynne Roberts with "Here on the Range With You.") Neither Roy nor Miss Hart seem terribly worried about their predicament and, sure enough, manage to get out of jail in time to perform the round-up of the title. Typical of the laid-back attitude of this Western is the ending where Roy, instead of the obligatory kiss, merely receives a handshake from Hart for his efforts. Rough Riders' Roundup was filmed by Republic Pictures at the ghost town of Ryolite, NV, and remains a pleasant enough early Rogers series entry.
