With this Canadian spot for the 2012 VW Jetta GLI, agency Red Urban Canada put a lot of work into a visual trick that looks like Tron doing doughnuts in an outlet mall parking lot. And I mean a lot of work. The ad's principal light-painting stunt, which employs beam-splitting techniques you don't see much outside of 3-D filmmaking, may look fake, but the making-of video exposes just how real it was. The film crew's unorthodox camera setup caught both the Jetta's crazy driving and the light trails it left behind. The cheesy epic music detracts from the overall experience, though, and the process behind this ad is way more interesting than the ad itself. Or the car, for that matter. But hey, nice effect.
