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more than the cars used by the top contenders: Jackie Ickx's Ferrari 312B relied on brute force to compensate for its outdated styling, whereas Jochen Rindt's Lotus 72 showed that radical aerodynamics represented a brave and (potentially) faster way forward.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 was killed during practice at Monza. He was to become the sport's first posthumous champion. Brunswick Films were pioneers in the embryonic days of Formula One production, when sponsors controlled the demand for footage, and before the era of global TV coverage began. They have skilfully combined film from their famous archive - including some previously unseen material - to create a review that captures the essence of a very special era in Grand Prix racing.
