Commentator Murray Walker's dramatic, excitable voice defined a golden era of Formula One and enthralled viewers across the globe. This is an intimate portrait of one the nation's treasures, and the inspiring tale of a man who, at the age of nearly 90, continues to break the mould.
The documentary accompanies the indefatigable Walker as he travels to Australia for the opening F1 of the season, relives his tank commander past and rides classic scramble bikes. The programme also delves deep into the archive to bring back to life some of Murray's most sensational moments in motorsport and beyond.
With contributions from Michael Schumacher, Lewis Hamilton, Nigel Mansell, Damon Hill and Jenson Button.
