Try to post a link from Movie List if possible. They have a good amount of trailers.
I’d say two really good trailers were:
** Dark City **
I remember seeing this trailer in the theater. I had no idea what the movie was about, still had no idea what the movie was about after the trailer, but wanted to see it immediately. It helps that the movie itself was fantastic.
I remember I loved the trailer for the Ethan Hawke version of Great Expectations- good music, pretty people, a little drama. Then I said, well, okay, that’s done with!
