As if we're not already excited enough about the Watch Dogs game, that features an exclusive extra sixty minutes of playable content at launch on the PS4 version, today Sony and Ubisoft have announced a movie is on its way too.

Ubisoft Motions Pictures, who plans to release an Assassin's Creed movie in May 2015, will work with Sony Pictures Entertainment and New Regency to develop the Watch Dogs movie.

The announcement was made at Sony's Gamescom conference where footage of Watch Dogs on the PS4 was also shown off. The game is about hacker Aiden Pearce who is able to control his city's infrastructure, from transport and security to databases and banks. The focus on the drama of the story should make for a brilliant film adaptation.

And it looks like there may be some interesting cross-over between the movie and game as Ubisoft Motion Pictures CEO, Jean-Julien Baronnet says, "this deal creates exceptional opportunities for us to merge the realms of the story-based cinematic experience with the interaction of the video game". We're hoping for a story extension in the film that continues further with a DLC for the game - but that's just hopeful speculation at this stage.

New Regency Productions, setup by Arnon Milchan in 1991, is responsible for great films like Fight Club, LA Confidential and Heat. Could this be the first great movie-game adaptation? Not if Assassin's Creed gets there first.
