Four Nights in Knaresborough is a play written by Paul Corcoran (now known as Paul Webb) and first performed at the Tricycle Theatre, London in 1999. It recounts the aftermath of the murder of Thomas Becket by four knights making "the worst career choice in history". Despite being an historical drama, the play uses modern language, including an abundance of profanity and slang. A film version of the play, scripted by Webb and titled Four Knights is to be produced by The Weinstein Company, directed by Paul McGuigan. Source: Wikipedia (en)
