Continuity mistake: After Elsie has been kidnapped, there is a scene where a little girl walks up to an old man to ask him for the time. A man notices this and walks towards the old man. The old man is standing in front of a light pole which casts a shadow onto the pavement. In another shot, there are no shadows near the light pole.
