Here is a British-produced biography of Alan Turing, the famous mathematician and the father of digital computers, who was chiefly responsible for breaking Germany's enigma code during the Second World War. Turing was also a homosexual, which was then illegal in Britain and in much of the world.
As it says on Youtube:
Hugh Whitemore wrote a shortened version of the play for television. This was filmed in late 1995, as a production of THE DRAMA HOUSE and WGBH BOSTON for BBC NORTH.The first transmission, to my knowledge, was on 17 September 1996 in Canada, by Showcase Television. It was shown in the United States as a Masterpiece Theater production on 2 February 1997. The first British transmission was on BBC1, 5 February 1997.
Filmed for television in a naturalistic suburban setting, rather than on a timeless, expressionist stage set, Breaking the Code inevitably sacrificed many of the elements that made it grip theatre audiences. No stagecraft magic of Derek Jacobi's real-time changes of age: instead the teenage Turing was played by a young actor.
