Sir Arthur John Gielgud, was an English actor and theatre director whose career spanned eight decades. With Ralph Richardson and Laurence Olivier, he was one of the trinity of actors who dominated the British stage for much of the 20th century. A member of the Terry family theatrical dynasty, he gained his first paid acting work as a junior member of his cousin Phyllis Neilson-Terry's company in 1922. After studying at the Royal Academy of Dramatic Art (RADA), he worked in repertory theatre and in the West End before establishing himself at the Old Vic as an exponent of Shakespeare in 1929–31.

Sir Ralph David Richardson was an English actor who, with John Gielgud and Laurence Olivier, was one of the trinity of male actors who dominated the British stage for much of the 20th century. He worked in films throughout most of his career, and played more than sixty cinema roles. From an artistic but not theatrical background, Richardson had no thought of a stage career until a production of Hamlet in Brighton inspired him to become an actor. He learned his craft in the 1920s with a touring company and later the Birmingham Repertory Theatre. In 1931 he joined the Old Vic, playing mostly Shakespearean roles. He led the company the following season, succeeding Gielgud, who had taught him much about stage technique. After he left the company, a series of leading roles took him to stardom in the West End and on Broadway.
