The trailer for Watchmen, set in a world where costumed crime fighting heroes have been outlawed, was posted on Empire earlier. Since then the trailer was taken down (for legal reasons or site issues I don't know) but Cinema Blend has it up if you can't wait. The trailer will also be shown in US cinemas before "The Dark Knight."

Watchmen, starring Patrick Wilson, Jackie Earle Haley, Malin Akerman, Billy Crudup, Jeffrey Dean Morgan, Matthew Goode, Stephen McHattie and Carla Gugino will be released March 6, 2009.

update: You can also find the new trailer on the Apple site!
