What are your favorite trailers?

[HeelsHater]

Watching trailers is part of the movie-going experience. At the theatre, I always look forward to catching new trailers before a movie starts. Other times, I'll see a trailer while watching TV that completely captivates me and makes me forget what show I'm watching. Last but not least are the trailers that I see for the first time online. If the trailer is great, it pulls me in and I have to re-watch it 5 or 6 times and then head to IMDB and other sites to find out as much as possible about the movie. Trailers can be misleading, and great trailers don't always equal great movies, but they're an essential part of movie-watching nonetheless.

So here's my question: what were the trailers that gave you chills, that you thought were badass, or that made you instantly say "I gotta see that"?

Here are a couple of my faves...

Terminator: Salvation - Incredible song choice (NIN - "The Day the World Went Away"). Gives me chills every time I watch it.

The Butterfly Effect - A little cheesier today than the day I first saw it, but I think Staind - "It's Been Awhile" makes the trailer awesome

Watchmen - Tons of slow-mo scenes. Another good song.
