In a world of cinematic double-dipping, studio interference, hard-to-reign-in directors, and a mania for deleted scenes and more-more-more footage, "director's cuts" have become common place. Rarely is it any big deal when a new cut is released -- there's often more footage to share, package, and sell off to fans.
Sometimes things slip through the cracks. The rediscovered footage of Metropolis -- or Clive Barker's Nightbreed for example -- they reveal a world where film clips disappear, only to be found years later, to our delight. And then there's other footage that should never see the light of day, the stuff that should slip into a vortex forever, like Richard Kelly's director's cut of Donnie Darko. But what about the cuts we haven't seen, but are definitely out there?
