The Zane Grey story King of the Royal Mounted had already been adapted as a comic strip by the time it was transferred to the screen in 1936. Robert Kent is cast as Sergeant King of the RCMP, while Rosalind Keith co-stars as heroine Helen Lawton. Helen arrives in Canada to claim a gold mine which she's inherited from her father (Frank McGlynn Sr.) The villain, a crooked attorney named Becker (Alan Dinehart), intends to cheat her out of her claim. Well, why not? He already killed her father, as King proves in the final reels. King of the Royal Mounted is sometimes confused with the later radio series Sergeant Preston of the Yukon, if only because Preston owned a dog named Yukon King. ~ Hal Erickson, Rovi
