For those of you who don't know, the movie Watchmen is based on the 1986-1987 graphic novel of the same name by writer Alan Moore and artist Dave Gibbons. The graphic novel takes place in an alternate reality circa 1985 where superheroes actually came into being in the late Thirties and early Forties. The United States is closer to ever to nuclear war with the Soviet Union. Richard Nixon is still president. Costumed adventurers (as the heroes call themselves) were banned under the Keene Act of 1977, but the murder of The Comedian triggers a series of events that will soon involved all of them. Along with The Dark Knight Returns and V For Vendetta by Alan Moore and David Lloyd, it is counted among the greatest graphic novels of all time.
Here then I present to you, courtesy of YouTube, the trailer to the movie Watchmen.
