Visible crew/equipment: When Calamity and Katie are driving back on the stage they are attacked by Indians before they arrive in town. Calamity starts shooting at them from behind the large suitcase with Adellaid Adams wrote on it. Initially there is no mark on the suitcase but halfway through the scene a black mark appears below the D of Adellaid and if you look very closely you can see the piece of string along which the arrow is shot.
Visible crew/equipment: When Hondo is being chased by the Indians after killing Lowe and gets knocked off his horse, when he jumps back onto the horse, look in front of the animal; you can see the white shirt of the man holding the horse.
