EXCLUSIVE: Jeremy Irons and Brendan Gleeson are joining the cast of Assassin’s Creed starring opposite Michael Fassbender and Marion Cotillard for director Justin Kurzel, New Regency and UbiSoft Motion Pictures; Fox is distributing. The live-action film is an adaptation of the wildly popular Ubisoft video game. Irons plays Cotillard’s father. Gleeson plays Fassbender’s father. This is one heck of a lineup as the production companies are very smartly reaching beyond the already established Assassin’s Creed brand and have put together a high-quality cast.

The Assassin’s Creed video games have sold over 91 million units. The film, about a man who attains the skills of a master assassin after finding out that he is a descendant of a master assassin who was part of a secret society of professional killers, is being co-financed by RatPac and Alpha Pictures. Frank Marshall, Arnon Milchan, Jean-Julien Baronnet, Conor McCaughan, Fassbender and Pat Crowley are producing. Bill Collage, Adam Cooper and Michael Lesslie scripted.

Irons has won an Oscar (Reversal Of Fortune), an Emmy, a Tony and also a SAG and Golden Globe. His more recent film work includes The Words with Bradley Cooper, the Bille August-directed Night Train To Lisbon; the upcoming The Man Who Knew Infinity; Focus Features‘ Race based on the true story of Jesse Owens and the 1936 Olympics which bows on February 19; Batman V Superman: Dawn Of Justice (also for release in 2016), in which Irons plays the role of Alfred Pennyworth directed by Zack Snyder; and The Correspondence (for 2016), directed by Giuseppe Tornatore.

Gleeson last worked with Fassbender on Trespass Among Us. He also just completed production on The Free State Of Jones and Alone in Berlin. The Irish-born actor starred in the critically acclaimed Calvary last year as well as the sci-fi actioner Edge Of Tomorrow. Next up for him is Focus Features’ Suffragette with Carey Mulligan, Helena Bonham Carter and Meryl Streep which opens October 23 as well as the Ron Howard-directed In The Heart Of The Sea which opens December 11 via Warner Bros.

Gleeson is repped by The Agency and Gothan/Principal. Irons is repped by CAA.
