This Companion explores the remarkable variety of forms that Shakespeare’s life and works have taken over the course of four centuries, ranging from the early modern theatrical marketplace to the age of mass media, and including stage and screen performance, music and the visual arts, the television serial and popular prose fiction. The book asks what happens when Shakespeare is popularized, and when the popular is Shakespeareanized; it queries the factors that determine the definitions of and boundaries between the legitimate and illegitimate, the canonical and the authorized and the subversive, the oppositional, the scandalous and the inane. Leading scholars discuss the ways in which the plays and poems of Shakespeare, as well as Shakespeare himself, have been interpreted and reinvented, adapted and parodied, transposed into other media, and act as a source of inspiration for writers, performers, artists and film-makers worldwide.
