STORY: Michael Fassbender to Star in 'Assassin's Creed' Film for New Regency, Ubisoft

Lesslie, an acclaimed English playwright, wrote Prince of Denmark, which was performed at the National Theatre in 2012. He also has penned a number of short films including last year's Skirt, directed by Amanda Boyle.

Ubisoft Motion Pictures, the 2-year-old film and TV division of French video game publisher Ubisoft, is developing Assassin’s Creed in close collaboration with New Regency. The two companies announced in October that they are partnering on the film.

Fassbender and Conor McCaughan are producing the actioner, which centers on a bartender who is captured by a secret corporation and sent back in time to relive the memories of his ancestors -- all of them assassins -- and retrieve ancient artifacts. New Regency and Ubisoft are now seeking a director and additional producers for the film.

Lesslie is repped by London-based Casarotto Ramsay & Associates.
