According to Mel Smith - friend of George Lucas and director of Radioland Murders - the creator of Star Wars is "buying up the film rights to dead actors". He says that Lucas plans to resuscitate them in future movies using 3D technology:
George has been buying up the film rights to dead actors in the hope of using computer trickery to put them all together, so you'd have Orson Welles and Barbara Stanwyck alongside today's stars.
Of course, this is the British tabloid The Sun, but knowing the amazing digital 3D actor work in The Curious Case of Benjamin Button and Tron Legacy, Mel Smith's revelations don't surprise me at all. Or in the words of Luke Skywalker:
This has so much evil potential for perpetrating crimes against common sense and good taste that it boggles my mind. [The Sun]
