In the third and shakiest installment of the Bourne series, secret agent Jason Bourne (Matt Damon) is chasing after an assassin named Desh (Joey Ansah). This pistol-packing gunman wants to murder Bourne's ally, Nicky Parsons (Julia Stiles), but our amnesiac super spy isn't about to let that happen. Eventually, Bourne catches up with the undercover killer, and the two throw down in possibly the best fight of the franchise. But before they can start beating each other with every random object in sight, Bourne first has to leap across an alleyway and crash through a window.
Rest assured, there's no CGI here, just old-fashioned practical effects. To film the scene, director Paul Greengrass found the perfect alleyway in Tangier, Morocco, and then had a stuntman leap from one building to another, smashing his way through a false window on the other side. It's simple and elegant, but things get even more impressive when you look behind-the-scenes. In order to get the shot, second unit director Dan Bradley hooked another stunt guy to a wire rig, gave the man a handheld camera, and had him follow behind Matt Damon's body double.
In other words, to get the scene, two stunt men had to make a daring leap through the air, with one crashing through fake glass and the other dangling from wires. Crazier still, Greengrass says they filmed the scene "a couple of times" to get everything right, and once the cameraman's harness actually got stuck, ruining the shot. In total, the entire chase and fight sequence took two weeks to film, culminating in one of the most memorable set pieces in recent action movie memory.
