Still struggling to come up with a good crawl idea (anyone got something please speak up). But this was fun to see.
Keep the real crawl, itself.
And then keep it going, and going. Tell the entire plot of the film. Maybe 3x longer than normal (or even longer). Pan down from the star field, through a bit of atmosphere, and onto the closing shot of the film. Iris wipe to the end credits.
Show a bit of credits, run them off the screen and pan down from those stars to however Revenge of the Sith actually starts.
(Can you tell I watched too much Monty Python, growing up?)
