Watchmen

Watchmen is a 2009 film based on the graphic novel (of the same title) written by Alan Moore and illustrated by Dave Gibbons. The story, originally released in a 12-part, full year series, concerned an alternate United States history in the post-World War II era where superheros were morally questionable in their actions and endured realistic life experiences, emotions and relationships while trying to rid the United States of crime.
