I used to devour trailers by the truckload, but too many give away too much. It's become absurd. One of the reasons i like that Christopher Nolan fella' so much is that he seems to have a degree of control over the way his films are marketed, and the trailers rarely give away anything of significance, or anything which might surprise you the first time you see the film.
Anyway, I can't really list too many films here, because there are too many to list. It's become a very common occurrence; we have a generation of filmmakers who are arguably better at making trailers than movies. Not that I blame them -- it clearly works sometimes.
The first recent film that comes to mind, however, is Ang Lee's Hulk. The teaser trailer was fantastic, and the later trailers were, too, even if they showed too many of the cool action moments. Obviously, the film itself as a muddled mess.
