Travers rides from town to recover the saddlebags riding a gray horse and swaps horses with Yak for a bay or chestnut one. Yet the two men who follow him make no comment about this obvious change.
When Travers is at the Matlock ranch on his initial visit, the tails on his neckerchief vary in position between shots.
There are at least three chase sequences where the close shots show a different background to the long shots:
- Anita leaving the ranch
- Travers and Yak pursuing the wagon with Anita and Matlock
- when Travers pursues the man who tried to ambush him as he left the Matlock ranch.
When Travers jumps into the river to rescue Anita, it is at a noticeably different point to where the wagon went in.
Matlock clambers out of the river completely drenched, but his clothes are dry when he steals the canoe. Similarly, Travers' clothes are completely dry when he captures Matlock.
The battery-operated flashlight was not patented until 1899, much later than the time portrayed in this film, although the exact date is never disclosed. The original patented design was also very different from the type Travers uses. The particular design used here wasn't available until around WWI.
When Travers is chasing the runaway stage, they are on a road with 1920s era telephone poles and a wires.
Despite the title "The Star Packer", Travers never wears a badge at any time in the film.
It is obvious whom the voice of the Shadow belongs to.
As Travers and Yak are putting the two bad guys into the jail cell, the one in the black hat is still carrying his holstered gun. No law man would allow a prisoner to keep his weapon at any time.
