Visible crew/equipment: At Lees Ferry when the stagecoach is crossing the river, there is a shot from on top of the stagecoach. As the camera pans over to the river, a clear shadow of the camera and its film magazine are visible.
Continuity mistake: When the stagecoach enters Tonto street, it's shadow switches sides between angles.
Visible crew/equipment: In the scene where Ringo (John Wayne) finishes talking to the Marshall and walks toward the stagecoach, watch the right hand top side of the stagecoach, the camera with a film reel can be seen and as Ringo walks towards the stagecoach it gently moves back behind the stagecoach. The camera appears to have some kind of a covering of black cloth and also the hand and part of the arm of the operator can be seen.
Factual error: The distance from Lee's Ferry to Lordsburg is over 500 miles, not a trivial distance by stage coach. But in fact, the stagecoach travels several times through Monument Valley, back and forth. Monument Valley is on Navajo Reservation, nowhere near the Apaches or Geronimo.
Factual error: This movie takes place in 1880. Near the end, Luke has a "dead man's hand" with "Bee" cards which did not start being made until 1892 (which is why 92 appears on the spade ace in those decks).
Audio problem: When the baby is born Dallas shows it to the men and says "It's a little girl" but her lips don't move when she says this.
Continuity mistake: In town, towards the start of the film, it goes from a street scene in front of the coach to a shot of Andy Devine sitting on the coach. From the street you can see the buildings behind the stagecoach, but when it goes to Andy sitting on the coach, the background is sky, not buildings.
Other mistake: The trajectory of the arrow that hits Mr Peacock in the chest seems impossible.
