Visible crew/equipment: When Travis and Jessie investigate what was reflecting sunlight, a Kodiak Bear attacks. When Jessie climbs a tree to get away from the bear, you can see a hand reaching down to help him get out of harm's way. (01:15:00 - 01:16:00)
Factual error: In the closing scene, E.J. Bellocq pictures Hattie and Violet with a Kodak Portrait Brownie No. 2. The Kodak Portrait Brownie No. 2 was not introduced until 1929, a dozen years after the movie takes place.
