Edgar Wallace (1875–1932) was a British novelist, playwright and screenwriter whose works have been adapted for the screen on many occasions. His films fall into two categories, British adaptations and the German "Krimi" films.

British adaptations His works were adapted for the silent screen as early as 1916, and continued to be adapted by British filmmakers into the 1940s. Anglo-Amalgamated later released a separate series of 47 features entitled the Edgar Wallace Mysteries, which ran from 1960 to 1965.

German Krimi adaptations The crime films produced by the West German company Rialto Film between 1959 and 1972 form their own subgenre known as Krimis (abbreviation for the German term Kriminalfilm (or Kriminalroman)). Aside from the Rialto productions, other Edgar Wallace adaptations in a similar style were made by the West Germans Artur Brauner and Kurt Ulrich as well as the British producer Harry Alan Towers.

Early history of the German Edgar Wallace movies 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, Karel Lamač 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. From 1934 to the mid-1950s, no German-language films based on works by Edgar Wallace were produced. Then, in the mid-1950s, the West German film distributor Constantin Film began plans for a series of films. Due to the perceived unpopularity of the crime genre in West Germany at that time, however, no film producer willing to take such a risk could be found, delaying the project until 1959.

The 1960s German "Krimi" film movement In 1959, the Danish company Rialto Film, with its producer Preben Philipsen produced Der Frosch mit der Maske (based on The Fellowship of the Frog), targeting the West German film market. The film (a.k.a. The Face of the Frog) turned out to be surprisingly successful and started a veritable fad of crime movies, known as Krimis (abbreviation for the German term "Kriminalfilm" or "Kriminalroman") which lasted until significant changes in the direction of the West German film industry in the early 1970s occurred. Rialto soon acquired the exclusive rights to nearly all the Wallace novels, founded a West German subsidiary company and, unconcerned by the many copycat productions by others, moved towards the artistic and commercial peak of the series in the early 1960s.

There were a total of 39 West German movies based on works by Edgar Wallace from 1959 to 1972. Beginning with Der grüne Bogenschütze (The Green Archer, 1960/61), the leading examples of the genre were produced by Horst Wendlandt and directed by Alfred Vohrer or Harald Reinl. Following Der Bucklige von Soho (1966), all of Rialto's Krimi movies were shot in color. Additionally, the original novels were increasingly disregarded in favour of original stories. From 1969 onwards, Rialto Film started four co-productions with Italian producers to minimize costs. Audiences began to lose interest in the genre, which ended with Das Rätsel des silbernen Halbmonds in 1972.

The German Edgar Wallace "Krimi" filmography (1959–72) These films were all produced (or co-produced) by Rialto Film of West Germany (Horst Wendlandt) unless noted otherwise. (Rialto co-produced 32 of the following 39 West German films.) Where the German title is different from the English release print, a translation of the German title is also provided.

Style in 1960s "Krimis" films The typical Krimi movie of the 60s contains a number of distinct stylistic traits, which not only makes the films a true series, but – seen in context with other, similar West German crime movies of that time – marks them as part of a true film subgenre as well.
