Instead of finding an Iraqi boy/actor, find found footage and comp it in over a screen that the character is running towards in the snowy desert!!! This could kickass: Found footage. Cut back to reveal screen in desert. Cut to running or if possible, pull-focus. Shoot with pull focus and without! identifiable color other than white. Use black stuff? Get blue paint?
And try to comp in "killing sucks" interview during mirror scene. If not, then at least the audio, sounding all recycled and shit. And get a shot tonight of the tank to take to class tomorrow. Remember to get silence in the space. Remember to get close-up on hand before completely taking down set.
