This is a film about free running or Le Parkour (hence to be called PK) and it is simply amazing. So what is PK? Well a few months back there was an advert for BBC1, with a man running over rooftops, making amazing leaps from building to building, flipping around and generally being athletic. Well that is PK in a highly developed form, and that man was one of the founders of PK. So PK is kind of skating without a board, it combines climbing and gymnastics with elements from martial arts. Its involves running through urban and built up areas, jumping and vaulting over obsticles and things in your way, clearing gaps, jumping down huge drops and so on. So the film centres around three of the sports founders, all three of them are french and they founned the sport in their home town years ago because they were bored! These three people are amazing athletes and the film is about them free running over famous London landmarks such as the Albert Hall and one of the countries Battleships!!! It is to put it bluntly amazing and awe inspiring, they literally defy gravity, (at one point one of them jumps 40feet off a gun turret on the ship!). At no point are any safety measures used, no nets or matts, the guys just know their own abilities and do not exceed them. This is an absolutly amazing DVD and one that every one should own.
