Guys/Gals...I realize I do not speak for everyone (maybe no one...ducks for cover), but I am of the opinion that if it isn't in the official, released film, it doesn't count.
Look, if some key or critical information ended up on the cutting room floor...then that is the sole fault of the editor and director.
If the studio interfered, and forced the director to excise important, key information, then it is still the responsibility of Director. In such a case, the Director has 3 possibilities:
1) Cave in -- which still makes him/her responsible, however "unfair" (especially to a new and upcoming talent)
-- or --
2) Push back and stand your ground -- which apparently Ridley did on his very first major motion picture ("Alien")
3) Walk away, or refuse to have your "name" associated with the picture -- this has happened countless times in the history of cinema.
In the previous example, there is no evidence that any of this occurred.
If it didn't make if from one of the "draft" scripts, to the final, finished shooting script (as appears in the film), then it is the responsibility of a whole chain of people.
Finally, if key/critical information is contained in some viral marketing release, it most definitely doesn't count.
The film has to stand on it's own, completely independent of external resources and/or "ex post facto" buttressing and band-aids...including marketing info as well as director/writer post-release interviews and explanations.
IMHO, if any of this bullshit is required to make sense of the film, and/or explain (away) plot-holes, incoherent character decisions/behavior, etc....then what you have is a fundamental failure in story-telling, period.
Yes, it is fun to review draft screenplays, and speculate on "what-if" scenarios, if only because we all are hard core "fans". But at the end of the day, you have to look at this from the eyes of a general audience, who only has information contained within the film, or from prior films.
