The opening credits state that the Royal Canadian Mounted Police (RCMP) was established in 1874. It was in fact in 1873, and it was the North West Mounted Police (NWMP), existing primarily in Western Canada. After the Métis Rebellion in the prairie provinces, the NWMP became a national federal quasi-military police force, and became the RCMP on 1 February 1920.
According to the review of the picture in the 14 December 1938 edition of Variety, Warner Bros. produced this film for only $400,000 - less than any Technicolor film to that date.
James Stephenson (Inspector Gore) would again play an inspector of the Royal Canadian Mounted Police in River's End (1940).
