Old Yeller (1957)

Factual error: In one scene where Travis walks out the door of the kitchen half of the cabin, there is a thermometer nailed beside the door. In the late 1860's, when the movie takes place, thermometers like that were not available.

Katie Coates: If that don't beat all. I never saw such a dog.
Travis Coates: And you won't never see another one like him.

Trivia: Travis, Ollis, and their mother all starred together in Swiss Family Robinson also. (Travis as Ernst, Ollis as Francis, and the mother as the mother).
