Henry Cavill and Luke Evans will co-star with Nicholas Hoult in the war drama “Sand Castle.”

The film will be directed by Fernando Coimbra, who helmed several episodes of Netflix’s “Narcos,” with Chris Roessner penning the script.

Mark Gordon will produce through his Mark Gordon Company banner along with Justin Nappi through his company Treehouse Pictures and Ben Pugh of 42. Brian Kavanaugh-Jones will exec produce.

Treehouse Pictures is fully financing the film, which Gordon has shepherded from its inception.

The movie is based on Roessner’s experience as a machine gunner in Iraq’s Sunni Triangle. The story centers on Matt Ocre (Hoult), who is part of a mission to repair a broken water system in the dangerous and unstable Iraqi village of Baqubah. While the people of Baghdad welcome the Americans as saviors, the villagers resist their presence and Matt and his unit must try to convince the community that they are part of the solution, not the problem, in order to save the town and get out alive.

Voltage Pictures is handling international sales for the film and will present the drama to buyers next month at the American Film Market. The producers currently hold U.S. rights.

Evans just wrapped production on Disney’s live-action “Beauty and the Beast” and can be seen next in “High-Rise.” He is repped by WME.

Cavill most starred in “The Man From U.N.C.L.E.,” with “Batman v Superman: Dawn of Justice” coming up next. He is repped by CAA.
