OK, I have some good news for anyone who is interested. I was cleaning out a closet the other day and found the infamous VHS tape that went with the interactive board game(I have no idea what happened to the game itself, though). Anyway, I watched the footage and I have to say that the Vader stuff is pretty well done. It's not JEJ's voice, but it's definitely the screen accurate costume and I believe Prowse himself was in the suit. Anyway, I'm going to burn this footage on to DVD for my personal collection and then if anyone wants the VHS tape maybe we can work out some kind of trade for it. You can contact me via PM to work out the details. Cheers!
