Trying to name the best movies about advertising is something we've all done, but the results are usually far from scientific. Take Crazy People for instance. Hilarious ads; not such a great movie. So, we decided to try to rank ad-related movies in some relatively accurate way. Thus was born the AdFreak Ad Flick Index, cobbled together from critic and user scores on Rotten Tomatoes, along with critic scores on IMDB.
Without further ado, here they are: The 25 best movies about the ad industry, as ranked by the ineffable judgment of dubious science. Watch the montage below—and below that, the list, with clips of each film.
