This is the DVD review of the 1970 Grand Prix Season - The Uncrowned Champion - which saw Jochen Rindt crowned posthumously as the 1970 F1 Drivers Champion.

1970 was the year of transition in Grand Prix racing; the season that pitched the old guard against a feisty new breed of racers intent on pushing Formula One forward into the new decade.

Nothing symbolised this battle more than the cars used by top contenders: Jackie Ickx’s Ferrari 312B relied on brute force to compensate for its outdated styling, whereas Jochen Rindt’s Lotus 72 showed that radical aerodynamics represented a brave and (potentially) faster way forward.

And with the technological battles came a fascinating season’s racing. Jackie Stewart was the defending champion but took nothing for granted. When different drivers won the first four races, Stewart, and the world, knew that the Championship was wide open. Thrilling battles ensued until triumph and tragedy came together in one fatal collision: on the 5th of September 1970 Championship leader Jochen Rindt died during practice at Monza. He was to become the sport’s first posthumous champion.

Brunswick Films were one of the few producers filming Formula One in the days before global TV coverage, multi-camera angles and official season review DVDs and videos. The previously unseen footage from their famous archive has been utilised to create a review packed with on-the-limit driving (including an in-car lap of Brands Hatch), great close-ups of the major personalities and intriguing paddock-side discussions that give the sense of a story unfolding as the season progresses – the story of ‘car wars’ and the battle between set-up, streamlining and engine power. It's very much a film of its time.
