At the same Star Wars Celebration V event in Florida where George Lucas announced the Blu-ray box-set arrival, he also showed off a missing scene from Return of the Jedi, which shows Luke making his lightsabre in a Tatooine cave.
The short clip was cut from the film, so we missed seeing Darth Vader cajoling Luke to join him on the Dark Side, as he tinkers in a dirty cave on Tatooine, constructing his new green lightsabre, after he lost his first one when duelling with Darth Vader.
In other important Star Wars matters, the producer of the first two Star Wars movies, Gary Kurtz, revealed that the original ending for Return of the Jedi was not included in the film you and I grew up watching - according to Kurtz, "We had an outline and George changed everything in it."
He stated that Han Solo was actually supposed to die, but "by that time there were really big toy sales and that was a reason", as "the toy business began to drive the [Lucasfilm]empire". [Geeks Of Doom and nineMSN via GawkerTV]
