VIDEO : ?Assassin?s Creed? Movie Adds Jeremy Irons and Brendan Gleeson

Jeremy Irons and Brendan Gleeson have rounded out the cast of New Regency?s adaptation of the popular video game ?Assassin?s Creed? starring Michael Fassbender. Marion Cotillard and Michael K. Williams are on board to star as well. Justin Kurzel is directing, with production set to begin in the early fall for a Dec. 21, 2016, release through Fox. The studio decided last September to move the project out of the 2015 summer window. Sources say Irons will play Cotillard?s father, while Gleeson will portray Fassbender?s father in the movie.
