The quotes in AFI's list were selected from a ballot that included 400 choices from American films that have deeply circulated throughout popular culture over the years to expand their historical legacies. 'Look at me, I'm the captain now,' from 'Captain Phillips' has also received full meme treatment, as has 'Why so serious?' from 'The Dark Knight.' There have, of course, been many worthy additions over the last decade and a half that warrant future consideration: Lines like 'I drink your milkshake,' from 'There Will Be Blood,' or 'I wish I knew how to quit you,' from 'Brokeback Mountain,' were delivered shortly after the cut-off date. It's only fitting, then, that the American Film Institute (AFI) in 2005 compiled a list of the greatest movie quotes based on feedback from more than 1,500 leaders in the creative community including film artists, critics, and historians. Notable movie lines become part of the cultural lexicon, working their way into pop culture, parodies, and-in the digital age-circulating as gifs and memes.
