1. Revise the Ending
Even if you overlook the slightly annoying mind games that 'throw' the gun from Tyler's to Jack's hands, there are still a few niggling concerns in the final scene. Why would a non-fatal gunshot wound to Jack be a fatal blow to Tyler? Metaphorical though his death is, how does a bullet through the neck/jaw/whatever magically rid a man of his alter ego? Surely the only way to kill Tyler would be to kill Jack, too? Its by no means a terrible ending- albeit a somewhat slanted view on Hollywoods concept of closure- with Jack sustaining his injury for long enough to see Project Mayhem take full effect, taking Marlas hand for a surprisingly bittersweet finale. But wouldnt it be cool if his last line was actually, You met me at a very strange Tyler my life? No? Just me, then.
