I've been in touch with Alex Newborn, a big fan of Star Tours who put together a DVD a few years ago. On his DVD he included a TV special on Star Tours hosted by Gil Gerard. Alex might be interested in lending a hand to this project.
Alex also pointed me to a torrent at mousebits.com for the video from the ride, which he says is the best he's seen. It's similar to the timecoded version on OCP's Return of the Ewok DVD, but it's MUCH better in quality. By my eye, it may even be a first or second generation copy. The only issue with the video is that it seems to have a yellow tint, but I imagine that some of you guys here could easily correct that :)
I know there's the C-3PO video for the inflight instructions (fasten seatbelt, no smoking, etc). Here's a low quality version: http://www.shadowfuture.net/bh/misc/safety.mov
Is there a copy of the video you watch while you're waiting to board (with the woman with the 80s weird hair)?
And isn't there a short video of 3PO thanking you after the ride is over?
