Another new viral marketing video for Watchmen has just gone live, courtesy of the viral marketing site TheNewFrontiersman.net. This video is a PSA, just like we used to have in grade-school classrooms, and announces the passage of the Keene Act, which made vigilantism illegal.

Directed by Zack Snyder, Watchmen is based on the 12-part DC Comics series written by Alan Moore and featuring art by Dave Gibbons. Starring in the movie are Patrick Wilson, Jackie Earle Haley, Matthew Goode, Billy Crudup, Jeffrey Dean Morgan, Malin Akerman, Carla Gugino, Stephen McHattie and Matt Frewer. The film is set to be released on March 6, 2009.
