In addition to his stage and radio plays, Emlyn Williams wrote plays for television: in 1968, A Blue Movie of My Own True Love, about a love affair that results in murder; and in 1976, The Power of Dawn, about the final moments in the life of Leo Tolstoy.
Williams wrote the screenplays or provided dialogue for several motion pictures, including his Friday the Thirteenth (1933; with G. H. Moresby-White and Sidney Gilliat), Evergreen (1934; with Marjorie Gaffney), The Man Who Knew Too Much (1934; with A. R. Rawlinson and Edwin Greenwood), and The Last Days of Dolwyn (1949). His script for The Citadel (1938; with Frank Wead, Ian Dalrymple, Elizabeth Hill, and John Van Druten ), based on the 1937 A. J. Cronin novel, was published in Foremost Films of 1938.
Williams also wrote two volumes of memoirs: George: An Early Autobiography (1961) and Emlyn: An Early Autobiography, 1927-1935 (1973). The first tells the story of his childhood and youth in rural and urban Wales; the second chronicles his attempts to make a name for himself on the London stage as actor and playwright. Williams’s interest in the psychology of killers, a concern of several of his plays, led to his account of the 1963-1964 Moors murders in England, Beyond Belief: A Chronicle of Murder and Its Detection (1967).
In his youth, Williams wrote several novels, but it was not until he was seventy-five that he actually published a novel, Headlong (1980), a variation of the “if I were king” theme. Its hero, Jack Green, who is an actor struggling to achieve success on the London stage, turns out to be the only living heir to the English throne when the entire royal family is wiped out in a catastrophe.
