Bernard Knowles the Director had an interesting career. He was the cinematographer on Hitchcock's 1939 classic version of the 39 steps. At the end of his career he was an uncredited director of 'The Magical Mystery Tour' .No biography is available for the writer Hamish Hamilton Burns, who is only credited with 3 episodes of Sir Lancelot. At this time it is known that several US movie writers who had been blacklisted due to the McCarthy hearings and couldn't work in the US, worked under pseudonyms in the UK, particularly on the TV shows, Sir Lancelot, Robin Hood, The Buccaneers, William Tell and their ilk.When you realize that, you realize that many of the plots of these series had an obvious socio-political subtext. And we loved those shows, did we not?
