Terence Dudley joined the BBC in 1958 and worked with them throughout his life in various capacities. He was a producer on the SF-flavoured The Big Pull, Doomwatch (working alongside Kit Pedler and Gerry Davis) and Survivors (the mid-seventies post-apocalyptic drama created by Terry Nation, although the two did not see eye-to-eye on how the series should evolve). He directed episodes of Out of the Unknown, Doomwatch, Softly, Softly, Detective, Colditz, Survivors, To Serve Them All My Days, Secret Army, All Creatures Great and Small and Doctor Who (Meglos). He wrote for Doomwatch, the Wednesday Play (A Piece of Resistance, 1966), Survivors and Doctor Who (Four to Doomsday, Black Orchid, The King's Demons), and the pilot of Who-spin-off K9 and Company.
