[On a formatting note: I've tried to both embed the trailers (where possible) and link to the trailers someplace where I know they won't be pulled. If there's no embed, blame YouTube. Just click the link on the movie's title and you'll get it.]
8. X2: X-Men United (2003)
I must've geeked myself out dozens of times on this trailer (the second clip after the decent-but-not-great teaser) in the weeks leading up to X2. Just lots of good decisions here, from allowing Brian Cox's character to deliver the bulk of the exposition to the focus on the sheer number of characters in the movie (always a strength of the X-Men flicks). Bonus points for including as many shots of sexy Aaron Stanford shooting fireballs as humanly possible.
Awesome trailer attributes: iconic performer
13. 28 Days Later (2003)
Perfect example of a great teaser, where glimpse after glimpse piles up in your mind and you end up seeing far more than you probably did. Then, in the last third, you get that tantalizing shot of Cillian Murphy alone in the middle of a deserted Picadilly Circus. Unexpectedly beautiful look at an unexpectedly beautiful (and terrifying) movie.
Awesome trailer attributes: teaser; creep-tastic; cool song/score
