Someone uploaded all four versions of the Thief and the Cobbler to Google Video. So is it possible that I could do the same?

I’ll upload all versions of Star Wars from the past to the present, explaining their changes. And in the description, I’ll post a disclaimer saying that it is not for profit or personal gain, it is strictly for educational viewing, as it is important to learn of the changes to a film. I’ll also put that the uploader was Lucasfilm Ltd., as the guy who uploaded the Thief put Miramax Family Films, the Completion Bond Company, etc.

I’d really like to do this, but I just don’t want to get in any trouble. Will it be all right if I do it? Or not?
