Long Camera Shot (*spoiler*)

This shot was done with a zip line and a steadicam. The line was strung down the side of the hill, the operator Jimmy Munro http://www.imdb.com/name/nm0614013/ sat in a bosun's chair rig on the zip line to make the shot.
The operator and actor have to be in synch for this type of shot to work, you'll notice that at one point Denzel gets too far ahead of Munro and the camera, when this happens Denzel does a quick turnaround smoothly interacts with the extras as he waits for Munro to catch up to him on the zip line. As Denzel goes to the right of the burning hut, Munro hopped out of the bosun's chair and pursued Denzel on foot for the rest of the shot. You'll notice that a plant blocks the shot for a few seconds, this is the point where Munro abandoned the chair and had to concentrate on keeping himself from planting his camera (and face) in the ground more than what was in the viewfinder.
The hallway scene (Denzel going through the labyrinth of corridors to find the dead agent) has some nice camera work in it too. The operator and actor had to be in synch here, Denzel pulls off the necessary pauses as he waits for Munro to get ahead of him seamlessly.
