So far, I've posted "Fifteen Minutes" for Van Helsing, Dracula (1979. No other version counts for the purposes of the game), Hannibal, Hidalgo, The Day After Tomorrow, Harry Potter and the Prisoner of Azkaban, King Arthur, and Phantom of the Opera. (Yes, those are the only ones online. If you've read any other movies, they weren't by me. ETA: Dammit, I did forget Troy. ) So many people want Lemony Snicket (and since I never closed the Snicket-Phantom poll, it's currently leading. You know, after the fact...) that I'm going to see if I can fit that one in sometime--in the next couple of months, I mean. So you can count that one if you like.
In the book, we've got Jurassic Park, Independence Day, Braveheart, Gladiator, Titanic, The Matrix, Harry Potter and the Philosopher's/Sorcerer's Stone, Spider-Man, Attack of the Clones, and Lord of the Rings (all three). All of these movies count as well.
Here's the game: Find me a movie with as many 15M actors as possible. I guess we can give separate points for "number of actors" and "number of 15Ms represented." (The example that came up in the comments was Timeline--four actors, four different "Movies in Fifteen Minutes." Well, three plus the future Snicket.) The LOTR, Star Wars, and Harry Potter casts ALONE should make this an interesting game.
So. I'll be gone for a couple of hours; y'all leave what you find in the comments. I don't know what we'll do with the answer, but it might well get its own "Fifteen Minutes" when time allows. That, and it's mostly just intellectual (or "intellectual") curiosity on my part. Have fun!
