Someone managed to get a clip on-line of the lost Star Wars scene from Jedi where Luke is shown crafting his Lightsaber. The full clip will apparently be included on the Blu-ray box set expected to come out in 2011. Hit the link below to see what is circulating. It's not much, but it looks real. Can't wait to see what they include in the 2015 version.
Update: 08/16 22:44 GMT by S : Lucasfilm complained, and YouTube took the video down.
