Richard Digby Day (born 27 December 1941) is a British stage director and international professor and lecturer. He is particularly well known for his work in the classical theater, and is considered to have a special penchant for the plays of William Shakespeare and George Bernard Shaw. He is Vice President of the Shaw Society, a Fellow of the Royal Society of Arts, and has staged more productions of Shaw's work than any other living director. His productions of Stephen Sondheim musicals have also been notable.
Digby Day has been Artistic Director of five major regional theaters in the UK: the Bournemouth Theatre Company (from 1966 to 1968); the New Shakespeare Company at the Open Air Theatre in Regent's Park (from 1968 to 1985); the Welsh National Theatre Company (from 1969 to 1971); the York Theatre Royal (from 1971 to 1976); the Nottingham Playhouse (from 1980 to 1984); and the Northcott Theatre, (from 1977 to 1980).
Additionally, his work has been seen in the West End and on tour extensively throughout the UK, Canada, Denmark, and Ireland. Particularly successful were his touring productions of Sondheim's A Little Night Music and Company, Shaw's The Devil's Disciple, Somerset Maugham's Our Betters, and J M Barrie's Peter Pan. He directed Geraldine McEwan at the National Theatre in Two Inches of Ivory, a production about Jane Austen that has been seen all over the world under the auspices of the British Council, the UK's official international organisation for educational opportunities and cultural relations.
