I TiVo-blogged the whole 3-hour AFI movie quotes show last night, so it's kind of silly to have anything more to say... but it just so happens I do.
Topic 1: short quotes. There were two one-word quotes that made the top 100, the predictable "Plastics" and "Rosebud." (Why not name your rock band "Rosebud Plastics"?) There were a lot of two-word quotes, including two that just repeated the same word. Those two were -- too bad I don't know HTML code to make the answer temporarily invisible so you can guess -- "Attica! Attica!" and "Toga! Toga!" Three other two-worders were "Hello, Gorgeous" and "Yo, Adrian" and "Here's Johnny" -- all are saying hi to a woman! Then there's "Lah-dee-dah, lah-dee-dah" -- which has always bugged me, because Annie Hall doesn't use it in the sense I've always heard it used in real life -- to mean "showily glamorous." One more two-word quote: "My precious." Think I got them all. Many three-word quotes. Basically, the quotes tended to be short.
Topic 2: movies I can't see why we care about. "Marathon Man." What is it? That repulsive dental torture scene? Are people out of their minds? Why would you look at one second of that?
Topic 3: attitude. Notice how many of the top quotes -- including #1 -- involve telling somebody off or daring them to confront the speaker. We love that.
Topic 4: final lines. People love a great closing line. For "Gone With the Wind," two characters got their closing line to count, even though Scarlett's is dopey.
Topic 5: does anyone say I love you? The synonyms for I love you on the list re "Here's looking at you, kid" and "You had me at `hello.'" Don't remind me of that "Love Story" quote. It's more of a precept than an expression of love.
That's all I've got... for now.
