Equus was presented in Baltimore, in 1979 by the Lovegrove Alley Theatre. The production starred a pre-Broadway Charles S. Dutton in the role of Dysart. Director Brad Mays did double-duty in the role of Alan Strang. A young actress named Lauren Raher played Jill Mason, and her real-life mother Rhona Raher portrayed Dora, Alan's mother.
Equus was revived in 2007 in the West End by producers David Pugh and Dafydd Rogers, starring Richard Griffiths and Daniel Radcliffe in the leading roles. The production was directed by Thea Sharrock, and opened in February 2007 at the Gielgud Theatre. The production attracted a lot of press attention, as both Radcliffe and Griffiths appear in the Harry Potter film series (as Harry Potter and Vernon Dursley). In particular the casting of then 17-year-old Radcliffe caused some controversy, since the role of Alan Strang required him to appear nude on stage. This was despite the fact that many other young actors over the years had performed the play naked. Radcliffe insisted that the nude scene was not "gratuitous" and that he should portray the character and the scene as called for by the script. Radcliffe has stated in interviews that he chose not to watch the 1977 film, as he did not want to be influenced by Firth's interpretation of the character. The 2007 London revival was then transferred to Broadway, at the Broadhurst Theatre, running through 8 February 2009. Radcliffe and Griffiths reprised their roles, and Thea Sharrock returned as director. The cast also included Anna Camp, Carolyn McCormick, Lorenzo Pisoni, T. Ryder Smith, Graeme Malcolm, Sandra Shipley, with Collin Baja, Tyrone Jackson, Spencer Liff, Adesola Osakalumi and Marc Spaulding. Radcliffe eventually received a nomination for the Drama Desk Award for Outstanding Actor in a Play.
The first illustrated edition of the play text was produced as a large-format artist's book by the Old Stile Press, with images and an afterword by the British artist Clive Hicks-Jenkins, in 2009.
Equus was revived in Houston, Texas for a limited run in July 2014 at Frenetic Theater. The production was largely funded by donations on Kickstarter and was well received by critics and audiences alike. Broadway World called the production 'dark, daunting and sensual' and commending its 'stellar cast'. Houston Press said it was 'astonishingly good... a must see' while Culturemap listed the show as one of the hottest shows of the year.
