KOH:EE is a great film, agreed, and goes to show that when you make story decisions simply based off running time and your ideas of what an audience may be willing to sit through, usually you'll make a weaker film.Off the top of my head, probably the earliest "director's cut" is Spielberg's CLOSE ENCOUNTERS (although since then he's removed the extra footage from the ending that the DC added). And Cameron probably was the one to start popularizing them, at least in terms of getting the movie-going public aware of what DC's were (ALIENS and THE ABYSS in particular were stand-outs, and THE ABYSS:DC, like KOH:EE, proved that a DC could actually be a much better film).
