Ever since it was announced that Gerard Butler would voice the captain in Tales of the Black Freighter, an animated film which brings a comic featured within Watchmen to life, people have wondered how the two films would be brought together. Now, thanks to a story revealed by Empire Online, we know that Tales of the Black Freighter will hit DVD four days after Watchmen's theatrical opening.

Watchmen hits theatres March 6, 2009, with the DVD of Tales of the Black Freighter arriving in stores on March 10. When Watchmen hits DVD itself, the first release will likely not contain Tales of the Black Freighter, with an "ultimate" edition hitting later on containing both releases.

Watchmen, based on the award winning graphic novel by Alan Moore, is set in an alternate 1985 America where costumed heroes are a part of the world's history, and the "Doomsday Clock", which measures the tension between the USA and the U.S.S.R. is constantly at five minutes to midnight. Rorschach, a vigilante who refused to retire when his teammates did, is drawn out by the murder of one of his colleagues, and pulled into a world-wide conspiracy with terrifying implications for the future of mankind.
