The website has posted a new video, filmed using a super 8 camera, that seems to be taken from a truck passing the accident after the situation has been calmed. Does it contain any secrets or evidence about the murder? Watch and find out for yourself.
Also some rumblings about runtime. Three hours versus two hours, twenty minutes. All I know is that when Fincher made The Social Network he cut it so short the first time through that he had to go back and flesh out scenes, hence utter perfection. Somehow I know that longer or shorter he will make it work either way.
