Let's take a second to review the process of listing "best movies". The only word that can really be used to describe the process is "arbitrary." In the case of the AFI's "100 Best" lists, the American Film Institute's "experts" -- over 1,500 "leaders from the creative community", including directors, writers, actors, cinematographers, and editors -- vote from a list of 400 nominated films on which 100 are the very best. The film must be feature-length and American.
