In World War Z, former United Nations inspector Gerry Lane and his family find themselves caught up in a living nightmare. A devastatingly fast-moving virus is racing around the planet, turning its victims into mindless swarms of killing machines. As governments collapse and entire regions are depopulated, Gerry is recruited by the remaining forces of the United States military to infiltrate the darkest corners of the world in order to find a cure – or else humanity faces total annihilation.

Directed by Marc Forster (Quantum of Solace), World War Z is the much-anticipated, loose adaptation of the novel by Max Brooks (Saturday Night Live). The movie stars Brad Pitt (Killing Them Softly), Mireille Enos (The Killing), and David Morse (Treme). In the clip featured above, Gerry is given the hard sell by both his former boss and a grizzled commander about his involvement in the operation.

This first full clip from World War Z is somewhat curious, in that it depicts a scene that is supposed to be tense, and yet features no action whatsoever. From its clipped military dialogue to its quickly-edited shots to the electronic drums of its score, the featured scene shows that the film is being positioned not as a horror film, but a slick techno-thriller.

The clip will do nothing to assuage genre fans’ fears that World War Z is doing all it can to separate itself from a traditional zombie yarn, much less its rather unique source material. That said, the scene does communicate the desperation and manic energy of the situation quite nicely. Even if World War Z doesn’t perfectly recreate the sensibility of the novel, the clip shows that it may yet end up being a genuinely suspenseful, compelling disaster-adventure-thriller hybrid – as early reviews have indicated

World War Z will invade theaters on June 21st, 2013.
