Factual error: As John Wayne walks back into the house after Martha Hyer drives away, the curtains on the window are seen to be flour sacks with "Gold Medal Enriched Flour" printed on them."Enriched Flour" was not created until the 1940's.
Continuity mistake: At the start when Mary gets off the buckboard she has a food basket with a couple of things but no cloth/bread, but upon entering the house the basket has a red and white check cloth and bread sticking out.
Trivia: This movie marked the return of John Wayne to work after having a cancerous lung removed nearly 18 months before. He insisted on doing all his own stunts to show the public that the illness hadn't slowed him down.
