Christian Bale and Oscar Isaac will star as two thirds of a tragic love triangle in a period film titled The Promise, EW has confirmed, setting up two heavyweight actors in a film from director Terry George (Hotel Rwanda).

As first reported by The Wrap, Bale (American Hustle) has been tapped to play Chris, an American reporter in the crumbling Ottoman Empire who falls in love with the same woman adored by a Middle Eastern medical student played by Isaac (A Most Violent Year).

The film—co-written by Oscar-winner George and Memoirs of a Geisha scribe Robin Swicord—will be set during the decline of the Ottoman Empire, which collapsed in 1922 shortly after its defeat in World War I, which witnessed the Armenian Genocide of 1915.

The Promise marks the first full-length feature from George since 2007’s Reservation Road, which starred Joaquin Pheonix, Jennifer Connelly, and Mark Ruffalo as a trio whose lives become intertwined after a deadly hit-and-run accident. His 2004 film Hotel Rwanda—whose themes of genocide and historical events are reminiscent of The Promise—earned three Oscar nominations, including Best Original Screenplay. No release date has been set for the film, which is set to begin production this fall in Southern Europe, reports The Wrap.
