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 not on set. ""He was as scary off camera as he was on it."
