Alfonso Cuaron is a film genius. He's is today what speilberg was in the 80's.
That doggiecam company that built the rig for the car, i live about 2 blocks from them.
anyone watching this who wants to get ideas for practicing visual effects, there's some great examples in this! occassionally i saw signs in the background that were greened over, or the side of the bus was all green. that's good exercises, replacing things like that, invisible effects. good practice tracking, blending in, rotoing things over top, etc...
i really want to see this movie again.
