Westerns are famous for allowing six shooters to fire endlessly without reloading. Filmmakers hope the audience wouldn't count the shots. But in this movie Jason Robards Sr. hides behind a rock and defends himself from Steve Brodie and his henchman by firing three shots -- from a double barrel shotgun.
When Bob Banning and Chito are fleeing from Rimrock pursued by the posse a bus is visible traveling along behind a rock outcrop.
When Morgan and Rocky pursue Ben and Judy Jason and kill Ben, they are both riding dark horses. Judy Jason identifies Bob and Chito as the killers even though Bob is riding a palomino.
