Although I generally prefer the postwar Tim Holt films costarring Richard Martin, I also really enjoy Ray Whitley, who made a number of prewar RKO Westerns with both Holt and George O'Brien. Whitley was a fine Western singer and also has a nice screen presence, and he's a real asset to films such as CYCLONE ON HORSEBACK.
In this entry Tim, Ray, and Lee "Lasses" White play Stan, Smokey, and Whopper, who contend with several devious, greedy men in a small Western town who are trying to disrupt Jeff Corbin's (Dennis Moore) contract to string telephone wires across the mountains.
BAD MEN OF TOMBSTONE) persuades Stan and his men to finish stringing the wire themselves.
That's a simplistic description of a movie which has a lot more story than some "B" Westerns, as plotting by various characters results in horses, bonds, and money constantly changing hands, while there are also horseback chases and gunfights aplenty.
Holt and Reynolds, who were around 22 and 23 when this was filmed, have a nice feisty sparring relationship which is fun to watch. The same year they also starred in DUDE COWBOY (1941). The following year Marjorie would costar in HOLIDAY INN (1942) with Bing Crosby and Fred Astaire.
CYCLONE ON HORSEBACK was directed by Edward Killy. It was shot on Southern California movie ranches by Harry J. Wild. Somewhat unusually for the Holt Westerns, the exterior scenes in the camp were shot in a soundstage.
CYLONE ON HORSEBACK is available on DVD in a fine print as part of the Tim Holt Western Classics Collection Vol. 4.
There's a trailer on the Turner Classic Movies site.
