I actually was looking for it last night during the trailer for the film adaptation of Alan Moore and Dave Gibbons's graphic novel. The book and film are set in an alternate-reality New York City in 1985, where superheroes and costumed vigilantes exist (and where Nixon's still in office after he drafted superheroes to help us win Vietnam). The WTC was and still is an icon of that city; I'm glad that the special effects people recreated it for this film.
(By the way, that Watchmen trailer looks amazing. We in the Dark Knight audience reacted with cheers, whoops and applause. The trailer for the remake of The Day the Earth Stood Still? ALMOST NO REACTION. Silence, and one "Oh" I could hear right afterwards. Not even an ironic "Whoa" in honor of Keanu Reeves. Bad sign. Of course, this is a film that NEED NOT HAVE BEEN REMADE IN THE FIRST PLACE ARGH.)
