Zemeckis is directing the film from a script by Steven Knight.
Graham King, who first developed the project and brought it to Pitt, will produce alongside Zemeckis and Steve Starkey. The movie will be produced through King’s GK Films banner with New Regency. Executive producers are Knight, Jack Rapke, Patrick McCormick and Denis O’Sullivan.
The pic, set in 1942, follows a spy (Pitt) who falls in love and marries a French agent (Cotillard) during a dangerous North African mission. Caplan will play Pitt’s sister in the thriller.
Production is set to start next week in Europe, and the film is expected to bow on Nov. 23.
Caplan was most recently seen in “The Night Before” alongside Joseph Gordon-Levitt and Seth Rogen and has the sequel to “Now You See Me” set to bow later this year. Her Showtime drama “Masters of Sex” has its season-four premiere this summer.
She is repped at WME, Rise Management and Jackoway Tyerman. The news was first reported by Deadline Hollywood.
