Paramount is reteaming “The Hurt Locker” director Kathryn Bigelow and writer Mark Boal on action-adventure “Triple Frontier,” with Charles Roven, Alex Gartner and Steve Alexander producing through their Atlas Entertainment banner.

“Triple Frontier” is described as a high-stakes ensemble project. Boal and Bigelow, who will both exec produce, sold the original idea together; the logline is being kept under wraps.

Boal’s writing the script, set in the notorious border zone between Paraguay, Argentina and Brazil where the Igazu and Parana rivers converge — making “la triple frontera” difficult to monitor and a haven for organized crime.

“The Hurt Locker” has turned in a solid box office performance since Summit released the Iraq war thriller, grossing $9 million in seven weeks of limited release.

Boal wrote the “Locker” screenplay after spending several weeks embedded with an Army bomb squad, and Bigelow shot the film in Vancouver and Jordan and set it in 2004 Baghdad.

Roven, who produced “The Dark Knight,” told Daily Variety he’s hoping to begin production on “Triple Frontier” next year. He’s in post-production on historical drama “Season of the Witch” and is producing “Warcraft” with Sam Raimi for Warner Bros. and retirement community comedy “Winter’s Discontent” with Larry Charles directing for Columbia.

Warner Bros. set Jose Padilha last year to direct “A Willing Patriot,” a terrorism-themed action thriller also set in the notorious border area.
