He is the only actor to play both Ian Fleming's James Bond 007 and the Doctor in Doctor Who (1963). He played Bond in a 1971 BBC radio adaptation of Agente 007 - Si vive solo due volte (1967) and was at one point considered for the role on film. He portrayed the Valeyard, a possible future, evil incarnation of the Doctor, throughout the 1986 series of Doctor Who (1963). He later reprised his role in the 2003 Big Finish audio drama "He Jests at Scars...".

He is a distinguished classical stage actor (including performances for the Royal Shakespeare Company and the National Theatre) who came into his own briefly in 1970s historical films, particularly as Czar Nicholas in Nicola e Alessandra (1971). He is also a familiar face (and voice) to British television viewers.

He was offered the part of Captain Striker (played by Keith Barron) in Enlightenment: Part One (1983). He later played the role of the Valeyard in the "Trial of the Time Lord" season of Doctor Who (1963), an amalgamation of the dark side of the Doctor between his twelfth and thirteenth regenerations.

He was considered for the role of Dr. Armstrong in Space Vampires (1985), which was taken by Patrick Stewart.

He was once considered for the role of James Bond during re-negotiations for Roger Moore's services. He did play James Bond on BBC radio for a version of Agente 007 - Si vive solo due volte (1967).
