George doesn't own the rights to THX-1138, so I'm hoping beyond hope that Warner Brothers includes the original cut when they put it out on blu-ray next year. But somehow I get the feeling that's not gonna happen. Would love to be surprised though.
It's the same situation with American Graffiti. Universal owns the rights to that one, and they could easily branch both versions onto the same disc.
Of course, I'm saying all this under the assumption that George didn't cut some kind of a deal to get more control over those movies.
