Sports as a war metaphor is the ultimate cliche, right? If you're a creative director, and you want to do another war-themed ad using a sport, you might pick the tougher events --boxing, football etc. Archery, and javelin, even.
But tennis? This is the game where the worst thing the baddies do is fling their rackets, and utter obsceneties at the unpire. Think again. Playstation2 has created an unforgettable commercial, a TBWA Madrid effort, where the 'gentleman's game' is played on a battlefield that could belong to any WW2 movie set --with some Saving Private Ryan groans and special efx. Shot in B&W, with only the balls in green, the action is funny and riveting. Funny, because thw warriors wear shorts, and white shirts for godness sake.
This is one commercial that makes you wish you owned a TiVo --to watch over and over again, which is rare for commercials these days. See it here.
