The Doctor's Moriarty is a 2|entertain DVD documentary looking at the origins and history of the Master. It explores the contrasts between the Doctor and the Master.
In keeping with the series' occasional use of anagrams to hide the Master's appearance, the contributors to this documentary are thanked with anagrams of their names. Thus, Barry Letts, Terrance Dicks, Katy Manning, Christopher Bidmead, Joseph Lidster and Robert Shearman are thanked in the documentary's credits as, respectively, Beryl Tarts, Dr Arctic Knees, Tangy Man Ink, Maids Birched-Pother, Sir Jots Helped and Master Ron Rehab.
