After reports suggested J.C. Chandor was circling the Paramount action-thriller “Triple Frontier,” sources close to the project have confirmed that the “A Most Violent Year” helmer has closed a deal to direct the pic.

Mark Boal penned the screenplay with Charles Roven and Alex Gartner of Atlas Entertainment producing.

The film is set in the notorious border zone between Paraguay, Argentina and Brazil where the Iguazu and Parana rivers converge — making “la triple frontera” difficult to monitor and a haven for organized crime.

Kathryn Bigelow was originally eyed to helm the movie, but after she decided to direct “Zero Dark Thirty” first, the film got shelved and she eventually left the project.

The studio will next try and lock in the large ensemble that it has wanted for the film. Sources say Will Smith is interested in starring and the dialogue ongoing, but negotiations have not yet begun between the two sides.

This marks Chandor’s first film following “A Most Violent Year.” He also previously helmed “Margin Call” and “All is Lost.”

He is repped by CAA and Frankfurt Kurnit Klein & Selz.
