Good luck with your project. Lucas' changes to THX are far more severe than the to the OT, and I don't evny the level of work you're going to have to put in to restore it.

I think some elements might be lifted from the Japanese pan and scan LD, like the albino lizard shot.

Has anyone seen this poster before?

Interesting that the student film version was shown in Japan alongside Star Wars.
