Even if it's never released, the movie deserves at the very least a better blu-ray release. Criterion, a new 4K scan, or, even better, a full-fat 4K disc release. A wonderful, hugely underappreciated film.
What does it take you to release the original long version of this unforgettable film, why are you making the fans suffer. Fans should march to pressure them to stop this torture
Andrew Dominik was interviewed about this, he says a longer version does exist, but it's not 4 hours long, he says it was 15 minutes longer, since the film is 2h 40m, adding those 15 minutes would've made it 2h 55m.
