Canadian Mounties vs Atomic Invaders (1953) is a Republic Movie serial starring Bill Henry and both produced and directed by Franklin Adreon. It was the sixty-second serial (of sixty-six) produced by Republic. Despite the title, this is not a science fiction serial. The plot is a northern cold war adventure involving secret missile bases and a planned invasion of the United States.
A foreign power, which is represented by their agent Marlof, attempts to set up secret missile bases in Canada to target the United States for their planned summer invasion. Meanwhile, acting on intelligence following the smashing of a spy ring in Montreal, Royal Canadian Mounted Police (RCMP) officers Don Roberts and Kay Conway go undercover in a settling party headed for the Yukon. Marlof also has agents, Beck and Reed, in the party en route to the site of the planned missile bases. Their attempts to disrupt the party only call the attention of the Mounties to the larger plot who, once the settlers finally reach their goal, continue to pursue the troublemakers, uncover their plot against the free world, unmask Marlof and bring them to justice.
Canadian Mounties vs. Atomic Invaders was budgeted at $172,795 although the final negative cost was $167,669 (a $5,126, or 3%, under spend). It was the cheapest Republic serial of 1953 and the most under budget of all Republic serials.
The next most under budget was, in fact, the preceding Jungle Drums of Africa at $5,082 (2.9%) under budget. Those were the only two Republic serials released in 1953, although the studio did re-release Adventures of Captain Marvel (as Return of Captain Marvel) and Captain America (as Return of Captain America) to pad out their release schedule, not to mention the serial Commando Cody: Sky Marshal of the Universe, which was originally intended to be a television series.
Though filmed entirely in the United States, early chapters in Canadian Mounties vs. Atomic Invaders are set in a snowy region of northern Canada referred to as Taniak and rely heavily on the use of footage from earlier Republic productions including the 1938 feature Call of the Yukon and serials King of the Royal Mounted and King of the Mounties. These are blended with rear projection scenes featuring the serial's cast on studio sets and a "snow-dressed" Republic backlot. Later chapters set in snow-free forest were largely filmed in the Big Bear Lake region of California's San Bernardino National Forest.
Special Effects by the Lydecker brothers
