Look at the scene where Marshall White (played by Harey Carey Jr) is shot by Curley Bill (played by Powers Booth). When White steps to the street the first time have your eyes fixed on the lower right of the screen by Marshal White's left boot. Note his pantleg is pulled. You can see the wire running up White's pantleg, which goes to the explosive charge in Actor Carey's chest for when Curley Bill shoots him. It is seen briefly on another cut of this same scene. It is only visible for about 2 seconds, if that. You may be able to see it if you pause at the right time, depending on your VCR qulity.
