Creating a viral marketing video is the latest craze in the advertising world and the latest player in this new genre is Ray-Ban with their clever prank spot 'Subway Running'. The ingenious commercial features a guy (wearing Ray-Bans of course) running through 5 subway cars as it leaves the station. The stunt of course is created using quick edits and other timeless camera tricks, but either way the stunt sequence is impressive enough to trick many people. The bigger trick though would be if people could figure it out that it was a Ray-Ban commercial all along.
