A lightsaber Darth Vader used in the Star Wars films "The Empire Strikes Back" and "Return of the Jedi" just sold at auction for more than $3.6 million.
The lightsaber was wielded by both actor David Prowse and stunt performer Bob Anderson, and is described as the primary dueling prop created for Vader's character in both movies.
The lightsaber was made from a 1950s camera flash bulb attachment and expertly modified by the production team into a lightsaber, bearing authentic signs of wear that serve as compelling evidence of its film-used authenticity.
Brandon Alinger, the CEO of Propstore, mentioned that they received a "cold call" about the lightsaber and were able to determine its authenticity and history.
The auction, which included over 1,000 Hollywood costumes and props, was expected to net around $10 million and offered virtual and in-person bidding at the Petersen Automotive Museum in Los Angeles.
