In 1922, Canadian Historic Features Limited made plans to adapt R. G. MacBeth's
Policing the Plains with the involvement of Harwood Steele, the son of pioneer Mountie
Sam Steele, but the film was not made. On 28 January 1924,
Arthur D. Kean purchased the rights to MacBeth's book for $5,000 (). Kean planned for a six-reel (6,000-foot) film with a budget of $40,000, but production difficulties increased the final cost to over $125,000 as it grew to an eight-reel film. Kean was the project's screenwriter, producer, director, cinematographer, and editor; he also handled publicity and some of the fund-raising duties. Kean believed in the ideal of a Canadian film industry that would celebrate Canadian and British history, values, and institutions. He also intended the film as a corrective to the clichéd and inaccurate portrayal of the RNWMP and its members in the numerous
"Mountie movies" that were churned out by Hollywood studios during the silent era. Through personal contacts, he was able to secure the co-operation of the RCMP, including the loan of period-accurate uniforms and equipment. Assistant Commissioner T. A. Wroughton, of the RCMP's "E" Division, served as the film's technical advisor, and led a squad of Mounties shown in the opening scenes. The Western Pictures Company announced
Policing the Plains in March 1924, and planned a summer release at the
British Empire Exhibition. However, the film suffered delays due to a host of financial, logistical, and technical difficulties. Much of the outdoor action was filmed on the
Blood Indian Reserve near Macleod. Filming was supposed to begin at Grouse Mountain, representing the
Chilkoot Pass, but it is unknown if this sequence was actually shot. Filming at
Green Lake near
70 Mile House started in March 1924. A nearby ranch belonging to Jack Boyd, a rodeo champion and cast member, was used as headquarters for multiple winter scenes. Modern-day scenes for the film's introduction were shot in downtown Vancouver. In July, the production moved to southwestern Alberta for several months. The town of
Macleod was holding its 50th-anniversary celebration at the time, and Kean took advantage of the occasion to obtain background colour and scenery for his feature. Many scenes were shot in the Macleod area, especially on the Blood Reserve. A replica of Fort Macleod was constructed across the river from the fort's original site. Early in 1925, more winter and mountain scenes were shot in and around Banff, Alberta. A horseback jump off a cliff attributed to
Jerry Potts was recreated by the film on 27 August 1924, by pushing a dummy horse and rider off a 150 foot cliff. 100 people from Macleod witnessed the stunt. In March 1925, Kean asked Grant Hall, vice-president of the Canadian Pacific Railway, for an investment of $10,000; Hall declined after seeing some of the footage. Policing The Plains Productions Limited was formed to strengthen the film's finances. Later in 1925, Kean reshot some scenes on the Blood Reserve, and filmed a buffalo herd at
Buffalo National Park in October.
Canadian Moving Picture Digest reported that Kean had used 1,650 natives, 75 covered wagons, 2,000 horses, and 1,500 cattle by October 1925. These figures seem exaggerated, and that quality is typical of Kean's often bombastic publicity for the project. There are no known references to the film’s production during 1926. In early 1927, however, Kean resumed shooting on the BC coast. Between February and April, he shot and re-shot sequences on Vancouver Island; these scenes dealt with drug smuggling, with Victoria Harbour and other local waterfronts used as locations. In April or May, he was filming near the RCMP barracks in Point Grey, where another stockade replica had been erected for re-takes of the whiskey trader sequence. Additional footage was also shot on a farm in Ladner, south of Vancouver. In April 1927, Kean mortgaged the 16,000 feet of existing footage for a $3,500 loan to finance the film's completion. Interior scenes were shot that summer in Trenton, Ontario, at the studios of the
Ontario Motion Picture Bureau. Principal photography was finally completed in August after three years and five months. ==Release==
