For authenticity reasons, Clyde Bruckman and Buster Keaton's The General (1926) was – for the most part – filmed on location in Oregon. Set during the #AmericanCivilWar, it's a comedic retelling of a popular war memoir about the #GreatLocomotiveChase.
Sadly it was a box office #flop, resulting in Keaton losing his independence and The General entering the #PublicDomain as early as 1954. Luckily for us that means we too can enjoy the views of beautiful 1920s Oregon: https://yewtu.be/watch?v=YWm587wKKVw (note: this version has the appropriate piano score but appears to be a missing few minutes).
