Terence Dudley

Terence Dudley (28 September 1919-25 December 1988) directed the Fourth Doctor story Meglos and wrote the Fifth Doctor stories Four to Doomsday, Black Orchid and The King's Demons. He was not a particularly favoured writer of Peter Davison, who was especially unhappy with Dudley's work on Black Orchid. (DCOM: Black Orchid)

Despite his association with the John Nathan-Turner era, he very nearly wrote the pilot for Doctor Who. When Verity Lambert and David Whitaker received Anthony Coburn's draft for "The Forest of Fear" on 26 June 1963, they were unhappy with the story's development. Lambert asked Dudley to quickly write a replacement. He declined, leaving them to somewhat unenthusiastically produce Coburn's An Unearthly Child. (REF: The First Doctor Handbook)
