On the trip from Skagway to Dawson, Stewart calls his horse by his real name: Pie.
One of the many films that the actor most people know as Harry Morgan is identified in the opening credits as "Henry Morgan." Born Harry Bratsberg, Morgan went by the name "Henry" (his father's name) almost exclusively in films from 1942 until the mid-1950s, when he transitioned back to Harry to avoid confusion with the humorist Henry Morgan , who was a popular guest on TV talk and game shows during the first two decades of television. Harry Morgan was last credited as "Henry Morgan" in Under Fire (1957), and was often credited as "Henry 'Harry' Morgan" on TV and in movies through the mid-1960s.
The Athabasca Glacier seen early in the trip to Dawson is actually in Jasper National Park near Calgary and Edmonton, Alberta. Global warming has caused a significant and visible retreat of the glacier since the year of filming. The glacier is retreating at the rate of about 16 feet per year.
Throughout the entirety of the film, Renee Vallon (Corinne Calvet) is never seen without wearing a hat.
The Finnish title of this film is "Seikkailijoiden luvattu maa", meaning "The Promised Land of Adventurers" in English.
