"Through the Force, things you will see. The future, the past, old friends long gone." Someone has just found a disc full of behind the scenes, never before seen footage from Return of the Jedi. Two clips were uploaded to a Facebook page yesterday: a silent 59 seconds of R2-D2 repairing Luke's X-Wing on Dagobah, and a minute of Frank Oz getting fed lines and doing Yoda like only he can (which, in the end, sounds like quite a strain on the ol' vocal cords).
There's apparently a full half hour of raw, unedited material where these came from, which will be rationed out in bits and pieces. EditDroid, the LaserDisc-based system developed by Lucasfilm used here, is now (somewhat predictably) defunct -- though it was a a key first step in the evolution of digital editing tools like Avid and Final Cut Pro -- so the whole thing is an artifact of epic proportions. See these, you must.
