Edgar Wallace was a British novelist and playwright and screenwriter whose works have been adapted for the screen numerous times.
His works were adapted for the screen as early as 1915, and continued to be adapted into the 1940s. In 1960, Anglo-Amalgamated started a series of 46 films entitled Edgar Wallace Mysteries which continued until 1965.
Harry Alan Towers produced a series of films the early 1960s in international co-productions with Germany:
The crime films produced by the German company Rialto Film between 1959 and 1972 form their own subgenre known as Krimis (abbreviation for the German term Kriminalfilm (or Kriminalroman). Other Edgar Wallace adaptations in a similar style were made by the Germans Artur Brauner and Kurt Ulrich, and the British producer Harry Alan Towers.
As early as the silent movie era, German film producers discovered that the novels of Edgar Wallace were easily adapted to the screen. The first German production of an Edgar Wallace story, Der große Unbekannte (The Unknown), was filmed in 1927. Wallace personally visited the production of the next movie Der rote Kreis (The Crimson Circle, 1929) in Berlin. The Crimson Circle was trade-shown in London in March 1929 in the Phonofilm sound-on-film system.
In 1931, Carl Lamarc adapted The Squeaker, one of Wallace's best known works, as the sound film Der Zinker. Adaptations of The Ringer (Der Hexer, 1932) by Lamarc and The Double (Der Doppelgänger, 1934) by E. W. Emo followed. (In the United States, The Feathered Serpent reached the screen as The Menace in 1932.) From 1934 to the mid-1950s, no German-language films based on works by Edgar Wallace were produced. Then, in the mid-1950s, the German film distributor Constantin Film began plans for a series of films. Due to the perceived unpopularity of the crime genre in Germany at that time, however, no film producer willing to take such a risk could be found.
