When I was an active contributor to IMDB, I spent as much time correcting info as I did adding it. I heard someone call it the Wikipedia of movies, that's not far off. The accurate info is indispensable, I just dislike when inaccurate info spreads.

I'm guessing (original) refers to the approximate running time of the earlier assembly cut that contained the extra scenes. But that wasn't ever officially released, there was never a finished version of the movie with those scenes included, so it's not right in any case.
