The process of aesthetic imaging in time is a unique and fascinating characteristic of cinema. Why, then, has temporality, and specifically duration, received so little attention in theoretical accounts of film experience? This book makes the concept of duration the central tenet in an understanding of cinema and spectatorship. From this vantage point, the book reviews two major strands of film theory: embodied viewing and the senses, and the film-philosophy of Gilles Deleuze.
