We gave you a peek earlier today at the set of The Expendables 3 in Bulgaria, but now Lionsgate and Millennium Films have officially announced that filming has started along with the full cast and a synopsis. Here’s the press release:

Lionsgate and Millennium Films will begin principal photography today on THE EXPENDABLES 3, the third installment of THE EXPENDABLES action-thriller franchise, with production shooting on location in Bulgaria and at Nu Boyana Studios in Sofia.

THE EXPENDABLES 3 will feature Sylvester Stallone, Jason Statham, Jet Li, Dolph Lundgren, Randy Couture, Terry Crews and Arnold Schwarzenegger returning to their roles in the first two films with Wesley Snipes, Antonio Banderas, Mel Gibson and Harrison Ford joining the all-star cast along with Kellan Lutz, MMA star Ronda Rousey, welterweight boxing champion Victor Ortiz and Glen Powell.

Patrick Hughes (RED HILL) will direct the film, with veteran Dan Bradley (The BOURNE franchise; MISSION IMPOSSIBLE: GHOST PROTOCOL, QUANTUM OF SOLACE) directing the second unit. THE EXPENDABLES 3 is written by Creighton Rothenberger & Katrin Benedikt, who previously teamed on OLYMPUS HAS FALLEN, and Sylvester Stallone. Avi Lerner, Kevin King-Templeton, Danny Lerner and Les Weldon are producing THE EXPENDABLES 3. Trevor Short, Boaz Davidson and John Thompson are executive producing. Lionsgate will release THE EXPENDABLES 3 in North America and the UK on August 15, 2014.

In THE EXPENDABLES 3, Barney (Stallone), Christmas (Statham) and the rest of the team comes face-to-face with Conrad Stonebanks (Gibson), who years ago co-founded The Expendables with Barney. Stonebanks subsequently became a ruthless arms trader and someone who Barney was forced to kill or so he thought. Stonebanks, who eluded death once before, now is making it his mission to end The Expendables — but Barney has other plans. Barney decides that he has to fight old blood with new blood, and brings in a new era of Expendables team members, recruiting individuals who are younger, faster and more tech-savvy. The latest mission becomes a clash of classic old-school style versus high-tech expertise in the Expendables most personal battle yet.

The production will be overseen by Lionsgates Jason Constantine and Eda Kowan.

The first two installments of THE EXPENDABLES have grossed nearly $600 million in combined global box office.
