There have been numerous attempts to adapt the superlative graphic novel Watchmen, which was written by Alan Moore and illustrated by Dave Gibbons, into a feature film. The first serious proposal to do so came in the late 1980s and for a long time director Terry Gilliam (director of Brazil and 12 Monkeys) showed interest in making the film. However, after numerous attempts to create a script, Gilliam was quoted as saying that the graphic novel was too complex and too amorphous for even him to adapt. Later acclaimed director Darren Aronofsky (Requiem for a Dream and The Fountain) was reported as a possible director, but this never came into fruition. Initially set to direct the film was Paul Greengrass (director of The Bourne Supremacy and The Bourne Ultimatum). However he was sacked during budget disputes at Paramount Studios, who were at the time meant to release the film. Since then Zack Snyder (director of the remake of Dawn of the Dead and of the film adaptation of Frank Miller's graphic novel 300) has been assigned the role of director and the film has been moved from Paramount to Warner Bros. Studios.
The film was released on March 6 of 2009. On July 21 of 2009 the film was released in both theatrical and director's cut editions on DVD. On November 10 of 2009 the film was released in an Ultimate Edition containing Tales of the Black Freighter animated sequences and linking scenes.
