“As part of the announcement that Star Wars would finally be coming to Blu-ray, George Lucas screened a never-before-seen clip from Return of the Jedi over the weekend, showing Luke Skywalker building his own lightsaber in a cave on Tatooine. But according to Mark Hamill, he never filmed that scene.

The deleted scene debuted at Star War Celebration V and shows Darth Vader telepathically urging Luke to join the Dark Side, while Luke construct, and ignite, his own lightsaber.”

Either way, we think it’s rad.
