The Assassinís Creed movie has a writer, according to The Hollywood Reporter, and that writer is Michael Lesslie. Youíve probably never heard of him.

He wrote a big play in London called Prince of Denmark, as well as a few short films. AndÖ thatís about it for this.

Lesslie joins Michael Fassbender on the team, who is not only starring, but also co-producing as well.

He's better known in theatrical circles. Last year he wrote National Theatre production Prince of Denmark, a prequel to Hamlet (a play written by some bloke named Shakespeare).

Has Lesslie been hired for his grasp of historical drama? A previous report suggested the Assassin's Creed film will take its cues from the first Assassin's Creed game, indicating a return to the Crusades-era Holy Land and to grumpy assassin AltaÔr.

Regardless, Lesslie will need to get to work quickly, as Ubisoft wants the Michael Fassbender-fronted film to shoot this summer, possibly for a November 2014 launch.

Ubisoft Motion Pictures, the publisher's new film division, is working with Hollywood studio New Regency on the project.

UMP and New Regency are also collaborating on a Splinter Cell movie starring Batman actor Tom Hardy.
