I'm procrastinating so here's a quick update:
Here are three of the best trailers I've seen in the past few months.
The Girl with the Dragon Tattoo : One of the best trailers I have seen in a long time. It's eye catching- the cutting and the music (I cannot wait to listen to the full version of that song- it sounds amazing) are really well done. Although watching the trailer again after watching the original Swedish version of the film, if you know the story, I feel like you can place the scenes you get quick glimpses of really quickly. I thought the original film was fine. It was a solid movie with an interesting mystery, but it was definitely one of those movies that relied more on plot than characters. There are various reasons why I'd rewatch a movie, but I can't imagine myself wanting to go out of my way to rewatch this one (not that it was a bad movie, it was interesting and solid) since I already know what happens.
Tinker, Tailor, Soldier, Spy: There's a newer trailer for this one floating around online but I far prefer the first one. It really uses the music well to establish this great, taut, tense mood. I'm really looking forward to seeing this movie.
Take Shelter: this looks intriguing.
Also a kudos for the Muppets for their parody trailers.
Here's to hoping there're good movies as well.
