This Element focuses on Sleep No More, the iconic immersive theatre production of Macbeth produced by the British company Punchdrunk. Sleep No More and the Discourses of Shakespeare Performance frames this Shakespeare adaptation as part of a system of ghostly citationality through which audiences understand the significance of the past in performance today. Moreover, despite its seemingly analog format, Sleep No More is discussed as a valuable site for media research. And the concept of 'uncanny spectatorship' is introduced to describe audience practice in Sleep No More and other performance contexts. Ultimately, this Element offers readers the opportunity to explore a set of concepts that are significant to the study of Shakespeare in performance and to consider the ways in which audiences interact with bodies, spaces, text, and media in Sleep No More and other immersive experiences.
