Os Bandeirantes

Although there are scenes that show huge buffalo herds with what looks like thousands of animals, large buffalo herds didn't exist at the time this film was made (1923). The buffalo had been hunted almost to extinction during the late 19th century, with millions of them being slaughtered, and its numbers hadn't yet increased enough to comprise large herds. Cameraman Karl Brown used small lead castings of various sizes of buffalo, placed the larger ones toward the camera and used diminishing sizes in the background for depth. All the castings were mounted on a series of moving chains, those in the rear moving very slowly while the rows of chains moved increasingly faster as they neared the foreground. The castings were hinged so that they moved with an undulating motion, which made them appear to be actual buffalo running. The chains were placed out of view and the mechanical buffalo were placed in front of a painted background containing distant buffalo. The result was a scene of "thousands" of buffalo, when in reality most of them were basically statues.

Jim Bridger is presented in this film as being a bigamist with two Indian wives. Bridger actually married three times, all to Indian women, but the first died before he married the second and the second died before he married the third.
