George Emlyn Williams was born in the tiny Welsh village of Pen-y-ffordd in 1905. As a Welshman with dark colouring and an unusual name, Williams appeared very different from popular interwar actors such as Laurence Olivier and Brian Aherne, both of whom performed in West End theatre at the same time. Unlike that other famous Welshman of the period, Ivor Novello, Williams steered clear of musical theatre and nightclubs in favour of writing and performing in plays exploring murder and criminal psychology.
After attending grammar school and undertaking some schooling in France on a scholarship, Williams won a scholarship to Oxford, where he became involved with the Oxford University Dramatic Society (OUDS). Williams was supposed to graduate in 1926, but instead of studying for his exams he wrote a play, Full Moon, which was put on at the Oxford Playhouse under the management of J.B. Fagan. Williams decided to move to London without completing his degree when Fagan offered him a small walk-on part in the production And So To Bed, in which Edmund Gwenn and Yvonne Arnaud appeared as the principal players.
This modest role marked the start of a long West End career, in which Williams combined acting with writing and directing, regularly casting himself as the lead for his own productions. In his autobiography, Williams presents the years from 1926 to 1935 as ones in which he finds his feet both professionally and in his personal life. After numerous failures and some mild successes, the book ends with the first West End performance of his play Night Must Fall, which Williams credits as his ‘first solid success’ – it ran for a year and a half before transferring to Broadway for another 64 performances.
Night Must Fall is based on a notorious murder case of the interwar period, the ‘Crumbles Murder’ case of 1924. Patrick Mahon, a charming Richmond-based salesman, struck up an extramarital affair with typist Emily Kaye. Kaye fell pregnant, and Mahon led her to believe that they would travel to South Africa to start a new life together. Instead, he murdered her in a cottage on the Sussex coast and dismembered and destroyed her body so thoroughly that very little of it was found during the police investigation. What particularly spoke to the public’s imagination is that, less than 48 hours after the murder, Mahon picked up another woman and spent a few days at the cottage with her, whilst Kaye’s partly-dismembered body was in the next room.
Williams combined this story with the equally notorious murder perpetrated by Sidney Fox, who in 1929 killed his own mother by strangling her and subsequently set her hotel room on fire to cover his tracks. In Night Must Fall, Dan, a charming man (modelled on Patrick Mahon) strikes up a friendship with a rich but cranky old lady and her niece Olivia. Whilst the niece suspects that Dan is a murderer, she still falls in love with him and helps him stay out of the hands of the police. Eventually, Dan murders the old lady and steals her money – although Olivia wants to help Dan escape, the play ends with him being arrested.
In his autobiography, Williams states that he had initially been interested in adapting the story of Fritz Haarman, a German serial killer who murdered at least 27 boys and young men in Hanover, in 1924. Williams was bisexual and identified with Haarman’s young victims: poor or homeless men, in some instances selling sex for money, lured back to Haarman’s flat with promises of food and shelter. ‘Yes, it could have happened to me’, acknowledges Williams. Although the story is clearly close to his heart, British theatre censorship laws absolutely precluded the depiction of a homosexual, paedophilic murderer.
Alongside this career as theatre author and actor exploring the darker side of life, Williams also appeared in films. One of his first appearances was as the comic best friend to the protagonist in the Oxford comedy Men of Tomorrow (1932). Although the film was a commercial failure, it did bring Williams exposure and he was voted the most popular British actor by the readers of Film Weekly, ahead of Leslie Howard and Jack Hulbert. This in turn landed Williams with a contract at Gaumont-British, where he wrote as well as acted. His first gig with them was writing the dialogue, and starring in, Friday the Thirteenth (1933). He subsequently worked on the Jessie Matthews vehicle Evergreen and supplied dialogue for the 1934 Hitchcock film The Man Who Knew Too Much.
Although his contract with Gaumont was not renewed beyond 1935, Williams stayed active in film for the remainder of the interwar period, and beyond. As well as adapting Night Must Fall for the screen, he also acted in a range of genres such as the comedy Night Alone and the thriller They Drive By Night (both 1938). In 1936, he was cast as Caligula in Joseph von Sternberg’s unfinished I, Claudius, opposite other such greats at Charles Laughton, Flora Robson, and Merle Oberon.
Later in his career, Williams toured with an innovative one-man theatre show called Emlyn Williams as Charles Dickens, in which he delivered parts of Dickens’ novels in a manner similar to how Dickens himself toured in the 19th century. He remained interested in murder, and wrote a book about the Moors murders in 1968. Williams continued to be active as a writer and actor until close to his death in 1987.
