He was brought onto Doctor Who (1963) by the script editor in the early 1970s, Terrance Dicks. The Doctor Who (1963) producers Barry Letts, Philip Hinchcliffe and Graham Williams all considered him to be among the best writers of the series. He offered to write for the revival, Doctor Who (2005), but was told by executive producer Russell T. Davies that his services were not required. Davies did not actually use any writers from the original series.

He is the only Academy Award-winning writer of Doctor Who (1963).
