Revealing mistake: When Hauk finds the president's escape pod, there is a fire burning on the right of the screen. The camera was poorly placed in this part as the fire is horribly reflecting in the lenses, causing a bad distortion on screen that is highly distracting and covers the pod.
Revealing mistake: When Snake and the others are running across the 69th Street bridge after the taxi is destroyed, Brain runs to his left, insisting that's the safe path. He gets blown up by a mine. We can see the bright lights of the FX spread out in front of him; the mine is exploding before he actually steps on it.
