25 October (production)


 * 1963 - One day studio filming took place at Lime Grove Studios for TV: An Unearthly Child. Margot Maxine, an extra hired as a member of the tribe, walked out at 3:00 after refusing to have her teeth blackened.
 * 2006 - The first meeting for series 2 of Torchwood took place in Cardiff. The arrangement at the time included Helen Raynor's "Toshiko story" and an episode by Russell T Davies. RTD did not end up writing a story for that series in the end. The concept for Chris Chibnall's Fragments was originally intended for the sixth episode, and Catherine Tregenna had already thought up the idea of Adam Smith and his self-titled episode.
