'Expendables 2' Stuntman Dies On Set: What Happened?

In the same week as the filmmakers are being sued for potentially ripping off another writer's script to write the original film, tragedy has struck the set of "The Expendables 2," as one stuntman died and another one was seriously injured in an explosion on the set of the film's production in Bulgaria.

According to MTV News, "the accident occurred while the second unit filmed at the Ognyanovo dam in Bulgaria. None of the film's stars were present during the incident, as the first unit was filming at a resort more than two hours away."

The name of the stuntmen and further details have not yet been released.

Production company Nu Image/Millennium Films released a statement on the accident:

"It is with great regret that we confirm this unfortunate accident. Our hearts go out to the families and those on the production affected by this tragedy. The filmmakers are working closely with the authorities in responding to and investigating this accident."

Set to be released in summer of 2012, "The Expendables 2" is the follow-up to the action blockbuster "The Expendables," focused on aging action stars Sylvester Stallone, Bruce Willis, John Travolta, Arnold Schwarzenegger, Jet Li, Jason Statham, Dolph Lundgren and Chuck Norris as mercenaries battling corruption.

Yesterday we reported on a Hollywood Reporter story about how screenwriter Marcus Webb has filed a suit seeking unspecified damages and a court-ordered block on 2012’s “The Expendables 2” for infringing further upon a story he claims he wrote.

Webb claims the original storyline for "The Expendables" was swiped by Sylvester Stallone and the movie's co-writer David Callaham.
