Chicago Sun-Times by Roger Ebert

It is a thriller, not a documentary. It's my belief that the nature of the neocon evildoing has by now become pretty clear. Others will disagree. The bottom line is: This is one hell of a thriller.

An expensive flop and the latest Iraq movie to be shunned by the mass audience, Green Zone was still the year's most visceral, thrilling entertainment.

Damon's prior appearances as Jason Bourne make him credible in this role.

Village Voice by J. Hoberman

A master of smash-mash montage and choreographed chaos, Greengrass is the best action director working today, adroit at producing the sense of everyone converging and everything happening simultaneously.

Bourne goes epic. A wham-bam actioner, but its pointed political subtext ensures Damon and Greengrass deliver their most provocative mission yet.

The Hollywood Reporter by Kirk Honeycutt

Christopher Rouse's rapid-fire editing nervously stitches the stunts, chases, fights and confrontations together. It's a remarkable film.

Bourne goes epic. A wham-bam actioner, but its pointed political subtext ensures Damon and Greengrass deliver their most provocative mission yet.

New York Daily News by Joe Neumaier

The cast is strong, and Damon is a dependable center for all this, a classic American good guy wanting to know what's rotten and why.

When Mr. Greengrass made "United 93," his 2006 reconstruction of one of the Sept. 11 hijackings, some people fretted that it was too soon. My own response to Green Zone is almost exactly the opposite: it's about time.

Los Angeles Times by Kenneth Turan

Made with daring and passion, it attempts the impossible and comes remarkably close to pulling it off. So close, in fact, that the skill and audacity used, the shock and awe of this highly entertaining attempt, are more significant than the imperfect results.

Austin Chronicle by Marc Savlov

No matter where your political gullibilities lie, Green Zone is a riveting piece of actioneering.

Arizona Republic by Bill Goodykoontz

To pretend that the film doesn't make a political statement is silly. Of course it does. It wouldn't be effective at all if it didn't.

Entertainment Weekly by Lisa Schwarzbaum

With Green Zone, though, the malaise has finally hit me. So while Damon's Miller uncovers the (inconvenient) truth of why the U.S. invaded Iraq in 2003, all I want to know is: How does he suggest we get out?

Variety by Todd McCarthy

Once Damon's one-man truth squad goes off the reservation and starts behaving too much like Jason Bourne for comfort, the film begins not only spilling more blood but also leaking crucial credibility.

Time Out by Joshua Rothkopf

Not since a Nam-scarred Sly Stallone asked, "Do we get to win this time?" in "Rambo: First Blood Part II" has an American action star been deployed to rewrite history so thoroughly.

The New Yorker by Anthony Lane

What lends the film its grip and its haste is also what makes it unsatisfactory.

New York Magazine (Vulture) by David Edelstein

It's also rather tawdry. The climax is as ludicrous as any Jack Bauer adventure, and Greengrass is always on shaky ground. Literally.

Boxoffice Magazine by Ray Greene

Green Zone is an exercise in commercial cowardice masquerading as a thriller about political bravery.
