Coolest Trailer of the Summer?

I caught this trailer before The Taking of Pelham 1 2 3 a couple of weeks ago, and I think it's the best one I've seen this year. It was certainly the biggest surprise. To me, nothing makes a better trailer than one that makes you think you're to going to see one movie, then flips you over by the end.



For the first few minutes I was thinking, "Why is a trailer for a documentary showing before a big summer action movie? Did I go into the wrong theater?"

But a new trailer for District 9 has come out since then, the movie is about a month away from and maybe you've seen more of the viral advertising than I have and weren't as surprised. I just enjoyed being genuinely fooled for a few minutes (and am always excited by potentially good sci-fi flicks).

(The Taking of Pelham 1 2 3 was pretty good, by the way. Even if John Travolta can't help but overact whenever he plays the bad guy. The dialogue was especially good, which it had to be, since that's kind of the entire movie. But I want to watch the original, which is now available on Hulu.)
