Yeah Predators really is one stunning looking movie, and technically well put together, these shots looks superb.
Ive always felt the scene where fishburne locks them in and the red flare lighting kicks in reminded me of the scene from Aliens where the xenos attack the medlab and the survivors escape thru the airshafts, it has the same look and feeling of escaping from the claustrophobic space to it.
I also love the shot where the actors fall off the cliff into the water and the camera drops down, still following them, and actually splashes into the water with them, superb!
Also the films overall color palette and sharpness of the image is astounding, just gives it such a mucky and grounded feel to it.
