Winchester ’73 (1950) was filmed primarily in Arizona, with location work done around the Tucson area and nearby desert locations. Direct filming sites include:

• Mescal, Arizona
• Old Tucson (Old Tucson Studios), near Tucson, Arizona
• Circle Z Ranch area near Patagonia, Arizona
• Sonoita/Mustang Mountains region in southern Arizona
• Saguaro National Park in Arizona
• Backlots at Universal Studios in California were used for some sequences

If you’d like, I can tailor this with precise scene-by-scene shooting locations or map them to specific moments in the film.
