Marion Cotillard will star with Michael Fassbender in “Assassin’s Creed,” New Regency’s live-action adaptation of the Ubisoft video game.

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.

“Assassin’s Creed” is co-financed by RatPac and Alpha Pictures. Producers are Frank Marshall, Arnon Milchan, Jean-Julien Baronnet, Conor McCaughan, Fassbender and Pat Crowley. Ubisoft Motion Pictures developed the project and is producing with New Regency.

Cotillard has been nominated for a best actress Oscar for “Two Days, One Night.” She won the trophy in 2008 for “La Vie en Rose.”

Cotillard, Fassbender and Kurzel are repped by CAA. The actress is also represented by Agence Adequat in France.
