The director - Tony Kaye - was very unhappy that the studio - New Line - saw fit to a) re-edit Kaye's submitted cut of the film without his consultation or approval, and b) allowed Ed Norton into the editing studio to offer his input. Kaye alledged that the released version was substantially different to the one he had submitted, and that Norton's role was now bigger than it originally was, and that he (Kaye) wanted his name remove from the film. As his name still appears he obviously failed to persuade New Line to do this. He then went on to sue New Line, for failing to protect his rights as the director when they allowed Norton into the editing suite, and his 'union' the DGA for refusing to even hear his case for having his name removed. One of the cavets of both lawsuits was that they were conducted in absolute secrecy, so I've know idea how they turned out.
