Adapted from the popular comic series, Watchmen was directed by Zach Snyder, the same man who directed the film 300.
The action takes place in 1985 in an alternative America, where superheroes are an integral part of everyday life.
While the clock is ticking towards the Apocalypse, a masked vigilante discovers a conspiracy that threatens all superheroes, past and present.
Watchmen will open in regular theatres, as well as IMAX theatres, on March 6.
