In the Star Wars movies, not only do they make multiple copies of the props we see on screen, but different versions, as well. These are divided into two categories commonly referred to in the industry as "stunt." Often, they are featured with the main characters, while the stunt versions are used for the "extras" in the background. Most of the time when a lightsaber is ignited on screen, it is a stunt version of the hilt. They are lighter and easier to wield while filming the exciting lightsaber duels and action scenes. In the case of the stunt lightsabers, there is usually a rod attached to the hilt so that the actors can actually duel and make contact with the blades. These rods are also invaluable reference points for the special-effects technicians to later digitally add in the signature glows of the lightsaber blades.
