Equus is a play by Peter Shaffer written in 1973, telling the story of a psychiatrist who attempts to treat a young man who has a pathological sexual fascination with horses.
Shaffer was inspired to write Equus when he heard of a crime involving a teenage boy who blinded six horses. He set out to construct a fictional account of what might have caused the incident, without knowing any of the details of the crime. The play is essentially a detective story, with the psychiatrist trying to understand the cause of the boy's actions while wrestling with his own sense of purpose.
Equus was revived in 2007 in London's West End, with 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 franchise. In particular the casting of seventeen year-old Radcliffe caused some controversy, since the role of Alan Strang required him to appear naked on stage. 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. Peter Firth gave more than 1,000 performances as Alan Strang; however, 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.
Following the West End run, Radcliffe has expressed his desire to revive the role of Alan Strang on Broadway in media articles and interviews and has speculated that, due to his current Harry Potter filming schedule, "Equus" would likely make its transfer to Broadway in late 2008. Richard Griffiths would reprise his role as psychiatrist, Dr. Martin Dysart, and other cast members from the 2007 West End production may join the Broadway run if this can be arranged; however, Radcliffe has stated in interviews that he and Griffiths are "definites" for a Broadway revival and that the reality becomes "more probable every day."
