I'm just thinking it's a pity George has never released the original Star Tours movie footage. Even if it were silent, it would still be useful.It would be cool to even try incorporating some of the shots used in that movie into our little edit. I'm sure we could get a few seconds of useful material out of that which could make the edit unique. This is the closest thing I've seen, and obviously it's worthless for an edit.

EDIT: Having said that, a little research led me to realize that the Star Tours video Return of the Ewok video from preserv.22web.net both might have a decent quality of the video. I really think there might be a few seconds of material that could expand the space battle a bit. Like I said, even just a few seconds can go a long way. Look at ANH:R where Adywan reused some ROTJ footage to great effect (it wasn't that obvious, Ronster ;) So knowing this makes me excited to have another source to draw upon!
