No Turn Unstoned is a collection of "the worst ever theatrical reviews" compiled by the actress Diana Rigg.[1] The first edition, published in the United Kingdom by Elm Tree Books in 1982 and in the United States by Doubleday, was followed by a paperback edition in 1983.
Rigg wrote to her many friends and acquaintances in the theatre and film industries and asked them to share their worst-ever reviews. She also researched theatre criticism and surviving comments from as far back as Ancient Greece.[2] During the early 1990s, Rigg toured university campuses, reading excerpts from the book. All of the proceeds from the speaking tour, and the book itself, were donated to a theatrical charity.[3]
