First of all, books are books. By nature of their medium they're not subject to the constantly changing world of home video formats, to say nothing of actual film. Plus it's only one person working on a book whereas a film has many.
Close Encounters: Columbia released a "Special Edition" not too long after the film's original 1977 release. I think this was 1980 or so. Correct me if I'm wrong, but the dvd edition does not have any added special effects that were found in the SE release, making it no more than a director's cut.
Apocalypse Now: both versions, enough said
Star Trek: The Motion Picture: Paramount and Robert Wise gave it somewhat of a Special Edition treatment for the dvd. Even though they didn't include the original theatrical cut, they did include every single altered shot in its original unaltered form on disc 2 of the set, in addition to deleted scenes and scenes from the television cut.
Blade Runner: the '92 (or was it '91?) director's cut is just that and nothing else. Besides, we're finally getting the original theatrical next year.
Any argument about "Lucas didn't have the time or money" is pointless. The movie was several million dollars over budget when it was released in May of '77. To my knowledge, the only studio interference was the removal of "Episode IV A New Hope" in the opening crawl. I'll grant Lucas that one revision because, hell, it had nothing to do with money or technology. No amount of money would have achieved the SE's cgi because the technology did not exist in 1977, so please, Go-Mer, don't say one thing when you mean another. Dykstra's motion control was a huge step forward in '76/'77, that was something that had to be invented, and Lucas tries to stomp all over that in 1997 with outdated cgi? If Lucas really means what he said in that quote, I doubt he has much self respect.
