Sir Henry Cooper was a true British sporting hero and a wonderful human being.
His death on 1 May, at the age of 76, prompted a flood of tributes to the man they simply called "Our 'Enry".
Cooper was British, European and Commonwealth Heavyweight champion, but never managed to win the World title during the uniquely competitive era of Muhammad Ali, Joe Frazier and Sonny Liston.
But he did memorably succeed in knocking Ali off his feet in their legendary 1963 bout at Wembley.
Loved by his family, his peers and even his opponents, this special BBC Two documentary will chart Henry's tough wartime upbringing, his most memorable fights, his iconic appearances on the small screen, as well as his remarkable journey into the hearts of the British public.
Sir Henry's two sons Henry and John also talk fondly and emotionally about their special dad, while Sir Michael Parkinson, Sir Bobby Charlton, Jimmy Tarbuck, Barry McGuigan and Frank Bruno are among the close friends who tell their personal stories of the champion who became a national treasure.
