Both Oscar Isaac and Ben Affleck are now confirmed as cast members for Netflix and J.C. Chandor's action/adventure Triple Frontier. The Triple Frontier project has been in development for several years, going (at least) as far back as 2010. At one point, the film was going to star Tom Hanks, with The Hurt Locker and Zero Dark Thirty director Kathryn Bigelow and screenwriter Mark Boal reuniting behind the camera. Actors such as Channing Tatum, Johnny Depp, and Tom Hardy have all either circled the project or been attached to star at different times over the past few years, but have all since passed to work on other films instead.
Triple Frontier gets its title from the border between Argentina, Brazil, and Paraguay and is expected to focus on a military black ops unit battling drug cartels in that region of South America. Details beyond that are unknown at this stage and the film itself appeared to be on the verge of collapsing a year ago, after Paramount Pictures dropped it. Netflix subsequently picked up the film and plans to begin streaming it as a Netflix Original movie sometime in 2019. With shooting on the project - which J.C. Chandor is now directing - scheduled to begin this summer, the movie's cast is currently training for the action-intense thriller.
Popsugar Celebrity has photographs of Isaac and Affleck practicing snorkeling and bodyboarding in Hawaii, in preparation for Triple Frontier starting production on the island of Oahu in May. The actors were spotted on the Hawaiian beaches with a couple of their costars in the film, in the forms of Charlie Hunnam and Garret Hedlund; actors recently seen in The Lost City of Z and Mudbound, respectively. Game of Thrones and Narcos actor Pedro Pascal is also slated to appear in the movie, along with Adria Arjona (Emerald City).
Affleck was reported as having departed Triple Frontier back in July 2017, so either that report was inaccurate or the actor found room in his schedule to work on the film after all. This is the first time that Isaac's involvement with the movie has been reported, though he has collaborated with Chandor before on A Most Violent Year. By the look of things, Isaac will have little to no break between shooting on Triple Frontier and reprising his role as Poe Dameron in J.J. Abrams' Star Wars: Episode 9 - seeing as Episode 9 begins filming this July, just a couple months after production starts on the former.
It was previously reported that Mark Wahlberg has been approached to replace Affleck in Triple Frontier, but it's possible that delays on The Batman and/or other DC-related projects led to Affleck being available. Wahlberg currently has two movies scheduled to begin filming this year - Instant Family and The Six Billion Dollar Man - before hitting theaters in 2019. As such, it stands to reason that he won't be appearing in Chandor's thriller in any capacity, supporting or leading.
As for the actual film: Triple Frontier certainly has the makings of something worthwhile, between its talented cast and intriguing subject matter. Chandor has emerged as a storyteller with a distinct stripped-down visual style and interest in exploring social/political topics through genre tropes, earning him a good deal of critical acclaim (and an Oscar nod for writing) for his efforts on films like Margin Call, All Is Lost, and A Most Violent Year. While Netflix has struggled to gain the favor of critics of late with Original Movies like Bright, The Cloverfield Paradox, and Mute, they've earned critical applause for director-driven offerings like Beasts of No Nation, Okja, and Mudbound in the past. All things considered, Triple Frontier has the potential to become another critical darling in that vein for the streaming service.
Triple Frontier doesn't have a premiere date yet, but is expected to begin streaming on Netflix in 2019.
