Obviously oscillating shadows in 3 successive scenes (all looking south) indicate poor continuity. As Juan de la Vega rides into town toward the Agry Saloon the shadows are toward the right indicating a morning shot. Right after Roy Agry is shot by Juan, the Sheriff and his men are seen running across the street toward the saloon; this time shadows are to the left (an afternoon shot) and there are clouds visible. A moment later Juan is shown running out of the Saloon and the shadows have switched back to the right (morning shot) and the sky has cleared up.
