I think Daniel Day-Lewis as Han Solo and Maggie Gyllenhaal as Leia would be spot on. I'm not sure about Luke yet, but if Boba Fett returns he might as well be played by Temuera Morrison and have Jeremy Bulloch give him advice on Boba's body language outside of action scenes. Even though I'm not a fan of Tim Burton, he probably could work on costume designs. Dark, weird etc. Of course the previous crew is free to return as well. I think David Fincher would be a good director. He worked at ILM, as a cameraman on Episode VI as his first job I think. I read somewhere that he also would have liked to direct Revenge of the Sith. As for the soundtrack, Brian Tyler might be able to pull of something worthy. What are your suggestions?
