 More than 40 have subsequently been produced in the West End, at the Royal National Theatre or by the Royal Shakespeare Company since his first hit "Relatively Speaking" opened at the Duke of York's Theatre in 1969.

In October 1983, the Riverside Shakespeare Company, then New York City's only year-round professional Shakespeare theatre company, inaugurated "The Shakespeare Project", based at the theatre company's home on the Upper West Side of Manhattan, The Shakespeare Center.
 "The Shakespeare Project" was the first major New York residency of actors from the Royal Shakespeare Company - with Edwin Richfield, Heather Canning, Christopher Ravenscroft, Jennie Stoller and John Kane (the later two from Peter Brook's "A Midsummer Night's Dream") - for a week of public workshops, panel discussions, seminars and performances at the company's Upper West Side theatre, The Shakespeare Center.
 The event was launched at a luncheon in the Shakespeare Room of the Algonquin Hotel attended by Joseph Papp, Helen Hayes, Frank Rich, Gloria Skurski, W. Stuart McDowell, and members of the Royal Shakespeare Company in mid October 1983.
 According to the "New York Times", over one thousand actors, students, teachers and stage directors, from the ages of 15 to 87, signed up for 22 sessions taught by some of the leading actors from London's Royal Shakespeare Company.
The World Theatre Season was a festival of foreign plays held annually at the Royal Shakespeare Company's Aldwych Theatre in London from 1964 to 1973, with a final season in 1975.
 It originated as a one-off celebration in 1964 organised by Peter Daubeny and the Royal Shakespeare Company as part of the celebrations for William Shakespeare's quatercentenary.
 In the 1950s, Peter Daubeny had presented foreign theatre companies, which gave him a knowledge of foreign theatre and served as a prelude to the World Theatre Seasons.
 Seven companies appeared at this initial World Theatre Season: Comédie Française; Schiller-Theater; Peppino de Filippo's Italian Theatre; Abbey Theatre; Polish Contemporary Theatre; Greek Art Theatre; and Moscow Art Theatre.
Sir Trevor Robert Nunn, CBE (born 14 January 1940) is an English theatre director.
 Nunn has been the Artistic Director for the Royal Shakespeare Company, the Royal National Theatre, and, currently, the Theatre Royal, Haymarket.

Twelfth Night (also known as Twelfth Night: Or What You Will) is a 1996 British film adaptation of William Shakespeare's play, directed by Trevor Nunn and featuring an all-star cast.
 Set in the late 20th century, it was filmed on location in Cornwall, including scenes shot at Padstow and at Lanhydrock House near Bodmin, with Orsino and his followers wearing uniforms that evoke the Austro-Hungarian Empire.
Bart Whiteman (1948-March 14, 2006) was a Washington, D.C. theatre actor, director, and producer.
 He founded the Source Theatre in 1977 and served as its artistic director until 1986.
 He was influential in defining theatre in Washington as well as reviving 14th Street.
 According to Christopher Henley, artistic director of the "Washington Shakespeare Company", "Bart was one of the half-dozen or so of the most seminal influences on and pioneers of what theatre in D.C. was and has become.
 He was part of that synergy -- along with Joy [Zinoman, founding artistic director of the "Studio Theatre"] and Tony Abeson [founder and director of the Washington Theatre Laboratory] -- that really began the small professional theatre movement in D.C. in the late 1970s."
 Trey Graham of the Washington City Paper said that the richness and diversity of modern-day Washington theatre "had a lot to do with his role as evangelist and cattle prod and crazy-ass visionary."
 Whiteman left the Source Theater after an incident in which it produced "Fool for Love" and "A Streetcar Named Desire" without paying royalties.
 Later, he became a theater teacher at Montgomery Bell Academy in Nashville, Tennessee and wrote editorials and theater reviews for "The Chattanoogan" in Chattanooga, Tennessee.
