This is exactly how 3D movies work. The modern way of making a movie 3D is to basically film the movie with two cameras very close to eachother, so that one film reel gives the appearance of being seen from the left eye and one from the right. Then once you have your movie, you project one reel onto one screen vertically polarized and the other reel onto a screen behind it horizontally polarized. Then with your 3D glasses, one lens is vertically polarized and the other is horizontal, so one lens can only pick up one screen and the other lens can only pick up the other screen. This is why when you look at someone who's wearing 3d glasses while you're wearing them, and you close one eye, one of their lenses appears black. Close the other eye, and their other lens appears black. Because each lens can only filter light that's polarized one direction, and the light is already filtered once by the other persons lenses, thus when you look at their horizontally polarized lens through your vertically polarized lens, none of the light filtered by their lens can get through your lens, creating a black effect. This .gif combines the right and left image, but since there aren't two screens on a computer and people don't wear 3d glasses everywhere, it can show them at the same time, so it just switches back and forth really fast to create the effect.
"We got this motion-capture camera that you program so the camera moves exactly the same every time," he added. "It was similar to what they did in 'The Matrix' with the flying bullets. They weren't wearing motion-capture suits. I wish I had thought of that. I would have made Will wear one for no reason. We just wrote joke scenarios of a night gone horribly wrong. We went to this bar on the Upper West Side [of Manhattan] and shot it in half a day. We cast stuntmen and women who could hold poses. Our special effects company, Evil Eye, added all these funny elements."
