Mark Hamill wants to esnure people are aware of what they’re bidding on in the upcoming Profiles in History’s Blockbuster Hollywood Treasures auction, being held in Los Angeles later this month. This from the BBC who also spoke to Roger Christian about the authenticity of the lightsaber.

Their website lists one of the lots as “The original Mark Hamill ‘Luke Skywalker’ lightsaber”, estimated to sell for up to $200,000 (£157,000).

But on Twitter, Mr Hamill explained it may not be a one-off.

“Be Advised,” the actor wrote, “There was no ONE lightsaber I used in the films, but many, MANY, both for myself & my stunt-double.” He ended the tweet with the hashtag, #BuyerBeware.

But the Academy Award-winning production designer for the original Star Wars film, Roger Christian, told the BBC the lightsaber is an original.

“There are five originals I handmade myself, and this is one of them,” he said. “It is real – I’ve got the Oscar to prove it.”

Mr Christian said the low budget meant he was putting together lots of different elements to make the props, meaning all the lightsabers are unique.

“I was supergluing things together – they all look different.”
