While at the RSC, Richardson played leading roles in many productions for director John Barton. These included the title role in "Coriolanus" (1967), Cassius in "Julius Caesar" (1968), Angelo in "Measure for Measure" (1970) and Iachimo in "Cymbeline". Work for other directors at Stratford included the title role in "Pericles" (1969), directed by Terry Hands; the title role in "Richard III" (1975), directed by Barry Kyle; and Berowne in David Jones' production of "Love's Labour's Lost" (1973). Richardson cited the role of Berowne as one of his all-time favorite parts. Richardson's "Richard II" (alternating the parts of the king and Bolingbroke with Richard Pasco) in 1974, and repeated in New York and London in the following year, was hugely celebrated.
