Rob found Star Wars news on the BBC website, in particular Lucas talking about real actors and not just digital recreations:

Star Wars director George Lucas has attacked the idea of using technology to recreate dead film stars. "It's something we are trying to stop happening, although you can't stop technology and you can't stop change," he said.

The director was at the Cannes film festival for the screening of his latest film, Star Wars Episode II: Attack of The Clones.

Advances in digital technology have raised the prospect of long-dead stars like John Wayne and Marilyn Monroe being brought back to life on-screen.

The technology has already been used in less conspicuous ways.

When veteran British actor Oliver Reed died during filming of the Roman epic Gladiator, some scenes were digitally altered to make it look as if he was present.
