Well i have been working on the scene with the Emperor and, mainly because of lack of usable dialogue, its looking that this scene will not be in my final edit. I don't want to add anything just for the hell of it and without the appropriate dialogue it would just be a redundant scene that doesn't need to be there. Plus i still want the scene to be in ESB and if i use most of the dialogue for ANH then that scene would have to be removed in ESB. But i am now looking at adding a very small extra scene as Vader flies away that will include a line of dialogue recorded for Vader that, originally for ANH, was inserted into ESB. So it looks like I'm going down the "hologram in cockpit" route now. I'll keep working on the Emperor scene but it is looking less likely to get finished.
