When Jeb escapes from his homestead in the dead of night, and is pursued by the Callums in a horse race, the scene suddenly shifts from night to day as Jeb attempts to shake off those chasing him.
Jeb's Medal of Honour consists of a five-pointed star, hanging from a multi-coloured ribbon which is surmounted by an eagle with open wings. The real Medal of Honour of this era consists of a five-pointed star surmounted by an eagle with open wings, hanging from a multi-coloured ribbon.
When Jeb goes back home from the war in Cuba they play Londonderry Air with a music box and he sings the lyrics of "Danny Boy" to go with the music. But the lyrics of "Danny Boy" were written for Londonderry Air in 1910, about 12 years after that war.
In the final chase, there are six Callum riders and one is sent back to get Ma Callum. When the Callums arrive at the old Rand homestead there are six riders who split up to surround the house. When Ma Callum arrives she is being driven in the wagon by the other Callum. In the subsequent scenes there are only six again.
When the Callums meet in the office after the wedding there are seven men including Grant. When the group stops on the cliff overlooking the ranch,again there are seven riders. When the chasers lose Jeff and stop on the cliff there are seven riders and then Grant sends one back for Ma Callum. As they ride to the old Rand ranch there are six riders.
After Adam is shot, a dummy is used to show his body rolling down the hill. The incline is not great and a stuntman could easily have been used, so the obvious dummy is a jarring note.
Although some of the outdoor vistas are breathtaking, the standard establishing shot of the ranch is shot indoors with a quite obvious painted canvas backdrop.
The lyrics to "Danny Boy" were not written until 1910, and were not set to "Londonderry Air" until ca. 1913.
