It's important to remember that the only Ady exculisve threads are the ones he started, many of the ideas on here or on other threads may not appeal to him and may appeal to other people.

The sandstorm scene only really exists as a few frames in an early trailer and few still images.

There may be more footage stuck in the Lucasfilm vaults so how much was filmed and remains is a bit of a mystery but that's all we have to play with.

Back in 1999 I wondered if the inclusion of the rather undramatic sandstorm scenes in TPM were originally going to be a revival of the idea (George likes to recycle ideas for one film in the others).

I can't see how it could be done with so little visual and no audio elements to play with.

Similarly the cave scene was never filmed.

There is a matte painting and a bit of a music cue but that's all.

SSWR's placing of Ben's ghost in the desert or my idea of sticking him in his hut carries some of the idea over but that's as close as I think we could get with the materials available.

Welcome The Concierge, your idea is interesting I'm not sure how to work it in to ROTJ, could Padme become a Force ghost when Mace couldn't? It could be a dying dream of Anakin but that might get in the way of the pacing of those crucially fast paced scenes.

I'll have a think about how it might be done.

That's not entirely accurate. Daniel's himself confirmed that his portion was completed at least. Hamill's we dont know. And I'm sorry but you don't create a fx storyboard for the optical department in Jan. of '83(mere months before release) and create a matte painting, expensive, without having completed some live action elements. And you certainly don't score it with music.
