He has performed with the Royal Shakespeare Company.
He was awarded the CBE (Commander of the Order of the British Empire) in 1979 and created a Knight Bachelor in 1997 for his services to drama.
Trained at the Webber Douglas Academy of Dramatic Arts in London, whose alumni include Terence Stamp, Hugh Bonneville, Rupert Friend, Angela Lansbury, Matthew Goode, Sue Johnston, Minnie Driver, Nicholas Courtney and Julian Fellowes.
Was nominated for Broadway's 1976 Tony Award as Best Actor (Play) for "Habeas Corpus."
When he first became a stage actor, his speaking voice was comparatively high-pitched so he had voice coaching to lower it and make it more imposing and sonorous. When he later started acting in films, his modified voice was too deep for the young parts that he was auditioning for, so he had further voice coaching to raise it about an octave. His present voice is pitched somewhere between these two extremes.
