The Hateful Eight is being released in two formats. Currently, a 70mm "Roadshow" edition is screening in limited theatres, and in a week, a different cut of the film is being released to wide distribution as a digital film.
I understand the differences with respect to the aspect ratio and film format between the two versions, and am not interested in those (nor, save for the sake of completeness, the presence of a printed program, an Overture and Intermission in the Roadshow screenings.)
However, the Roadshow edition of the film is also longer (I've seen conflicting numbers, but the most commonly cited are 6 and 20 minutes longer - I suspect the latter number includes the overture).
What I'm curious about is what, if any, are the specific narrative and dramatic differences between the two versions of the film? I find it hard to believe that you'd get even six more minutes just lingering on landscapes in a film that is as entirely interior as The Hateful Eight.
