The following is a very rough draft. I’m still reviewing a couple of movies that may possibly make it to this list, and the order is still very temporary. As far as trilogies (or sagas, in the case of Star Wars), I listed my favorite one, much like my Top Ten Video Games, in parentheses. In these cases, I highly enjoyed the entire series (or felt that the series as a whole represented masterful film-making, while any one alone wasn’t particularly special), but just listed my favorite one. In other trilogies where I just loved one movie out of them, I will just list that movie without any parentheses, like in the case of Godfather.
EDIT 08-26-07: I made some more modifications, adding a few new movies and also removing some. I really want to only focus on movies that I feel really matter in the grand scheme of things: where the movie transcended the screen and tugged at my very existence.
