Hmm. Ok that wasn’t as clear as I wanted it to be.
Let me try this. If a movie uses some sort of gimmick like a dream sequence, there seem to be levels of the “reveal” of that gimmick.
Example 1: In the Sixth Sense the gimmick is revealed at the ending of the movie itself.
Example 2. In the movie Secret Window the imagery used to suggest that we are entering the world or viewpoint of Johnny Depp’s character (by the camera zooming in and then going “through” a mirror)
is in the film but the explanation by the filmaker is in the extras of the DVD.
What I don’t understand is what the rationale of keeping a movie gimmick secret for this long would be. Why would Spielberg keep mum about it? What’s the point? If not him, then the editor, the PA’s, the script supervisor? Would none of these people have spilled the beans by now?
If there is no objective proof of the ending being a dream then which makes more sense?
a) no proof in needed because the film is literal.
b) no proof is available because everyone involved in the production with knowledge of the gimmick signed a non-disclosure agreement and kept to it.
I vote for a.
