The Second recurring Master in Doctor who(but technically the 4th incarnation)
Reportedly, it was his performance as Rev. Emilius (in The Pallisers) that led to him being offered the role of the Master by John Nathan-Turner, who had worked on The Pallisers seven years before becoming producer of Doctor Who.[4] Ainley first portrayed the Master in the 1981 serial The Keeper of Traken and appeared in almost every season up until the cancellation of the original series in 1989, including its final serial, Survival.[5]
Ainley's Doctor Who appearances included: The Keeper of Traken (1981), Logopolis (1981), Castrovalva (1982), Time Flight (1982), The King's Demons (1983), The Five Doctors (1983), Planet of Fire (1984), The Mark of the Rani (1985), The Ultimate Foe (1986) and Survival (1989).
He later reprised the role for the 1997 BBC computer game Destiny of the Doctors.
Ainley's great love of the role is often cited in documentaries and DVD commentaries. Script editor Eric Saward claimed that he introduced himself over the phone by saying "This is the Master" and then would laugh. In the commentary and documentary for The Mark of the Rani, both Colin Baker and Kate O'Mara say that "He only ever wanted to play the Master." Baker remarked that he could afford this luxury because he had built up a private income by the mid-1980s and had inherited a considerable sum of money from his father. In "Cat Flap: Making of Survival", Sylvester McCoy confirms that all he ever wanted to be is the Master, and he kept his role active, even when not on set. "He was as scary off camera as he was on it."
