One of several feature-length collaborations between Disney Studios and Canada’s Cangary productions was released on this day in 1961, Nikki, Wild Dog of the North. The film, which took three years to produce, was shot with an all-Canadian cast and crew near Banff, Alberta, which included four weeks of freezing temperatures. The film follows the adventures of a wolf dog who, while traveling with his master, encounters an orphaned bear cub, and the natural enemies become fast friends before continuing on a dramatic journey for survival.
