I've always been quite fascinated with the amount of research and development that went into several of the attractions (and the park itself) of Disneyland Paris, and I just came across this pre-opening video that shows how the Le Visionarium attraction was filmed and created. It is very interesting, and features many of the important scenes not featured in the American version "The Timekeeper" and several interviews with the actors.

I was most impressed with the filming of the scene in Moscow, and the giant Mickey balloon just steps away from Lenin's Mausoleum and Soviet Soldiers.
I have been wondering where this program was shown, it is very interesting. It reminded me of the BBC2 documentary from 1995 on Space Mountain that was also made in the same style, but much longer.
