Harry Carey Jr. rode his own horse called "Mormon" and Ben Johnson rode a famous movie horse called "Steel" that was owned by his father-in-law "Fat" Jones, who ran the most well known horse renting stable in Hollywood. In the galloping scenes Johnson rode Steel's stunt double Bingo and was quoted as saying he was just a passenger as "Bingo" thundered down the hills. According to Carey, Steel and Mormon became very attached and ruined quite a number of scenes by calling out to each other.

Ben Johnson did all his own stunts.

In the scene where Travis gets bucked off his horse after Denver throws water on it, Ben Johnson did his own stunts. They used a genuine rodeo bucking horse and John Ford promised Johnson if he rode the horse he would not have to do any dialogue for the day, which apparently pleased Johnson. He lasted four bucks and came off so hard he was almost knocked out. Unfortunately, the shot was ruined by one of the wranglers running out to him and asking if he was all right as he lay on the ground. Johnson had to get up and ride the horse again. This time he lasted ten bucks before he bailed off and Ford got his shot.

Prudence arrives after Wiggs and Adam, and stands behind them, in front of Sandy on the fence. Between shots she appears near Sandy, with her back to him.

After Denver throws the bucket of water on Travis and he falls in the dirt, his arms and back are covered in dirt, in the next shot there is hardly any dirt on him, and he did not have time to brush it off.

A Golden Retriever is shown in close-up during the credits sequence. Goldens were originally bred in Scotland beginning in the 1860s, and were not registered in America until 1894. It's "possible' that a Golden could have been accompanying the wagon train, but very unlikely.

Travis Blue: Sure hope I see you again, Miss Denver.

Sandy: I left my gal in Old Virginy...

Sandy: By Golly, I bet it's going to be hotter then...
