Ainley's swarthy appearance tended to get him parts as villains, though an early regular role on British television was as Det. Sgt Hunter, sidekick to
William Mervyn's Chief Inspector Rose in the second series of ''
It's Dark Outside in 1966. Other notable roles include a subaltern in the 1969 film version of Oh! What a Lovely War, Dietz in the 1974 film version of The Land That Time Forgot'', Ainley first portrayed
Nyssa's father Tremas in the 1981 serial
The Keeper of Traken, which led to him becoming a new embodiment of The Master. From then on, he appeared in most seasons up until the cancellation of the original series in 1989, including its final serial,
Survival. Ainley's incarnation of The Master spanned four different incarnations of the Doctor. His appearances included the following serials:
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 was the Master, and he kept his role active, even when not on set. "He was as scary off camera as he was on it." ==Personal life==
