Caryl is played by Lois Wilde, but despite her title-character status Ms. Wilde is third-billed behind a pair of "juniors." Doggy star Rin Tin Tin Jr. and human hero Francis X. Bushman Jr. handle all the rough stuff, while Caryl alternates between waiting patiently and requiring rescue. Rinty Jr. is the sidekick of Mountie Bushman Jr.; together they get their man (Robert Walker) after five reels of rugged adventure. The original story is credited to Northwoods specialist James Oliver Curwood, though chances are that he merely collected the royalties and ran. Caryl of the Mountains was released by a production firm called Reliable, which usually wasn't. ~ Hal Erickson, Rovi
