The Empty Space is a 1968 book by the British director Peter Brook examining four modes or points of view on theatre: Deadly; Holy; Rough; and Immediate. The book is based on a series of four lectures endowed by Granada Television and delivered at Manchester, Keele, Hull, and Sheffield Universities in England. The first lecture, on The Deadly Theatre, was delivered on 1 February 1965 at Manchester University. The lecture series helped to fund his long-planned trip to Afghanistan.
