The Edgar Wallace Mysteries is a British second-feature film series, produced at Merton Park Studios for Anglo-Amalgamated. There were 47 films in the series, which were released between 1960 and 1965. The series was screened as The Edgar Wallace Mystery Theatre on television in the United States.
Producers Nat Cohen and Stuart Levy acquired the film rights to all of Edgar Wallace's books and stories in 1960. The resulting adaptations were loose, very few using Wallace's original titles, and there was no attempt to set them in the period in which he wrote, probably to eliminate the need for elaborate costumes and sets. A 1962 article in Scene magazine quotes £22,000 as the budget for an episode in production at the time of reporting. The majority of the films played as supporting features on the ABC Cinemas circuit, which was Anglo-Amalgamated's usual outlet; but ten of them were allocated to the rival Rank circuit, with screenings in their Odeon and Gaumont cinemas.
Most of the series featured a uniform title sequence, in which a shadowed bust of Edgar Wallace revolves slowly against a backdrop of swirling mist, to the accompaniment of the "Man of Mystery" theme written by Michael Carr. "Man of Mystery" was later recorded by the Shadows and became a number 5 hit record in the UK.
The film, Violent Moment (1959), was later released with the Wallace Mysteries' credits replacing the originals, even though it was not part of the series. According to Kim Newman, insufficient episodes were available for American television, for the series was still in production; hence, the distributor Anglo-Amalgamated attached the 'Wallace Mysteries' credits to some of its other mystery and crime films (such as House of Mystery, 1961) and thereby expanded the series.
The series has been shown on television. In Britain, it was shown by ITV in 1968 under the title Tales of Edgar Wallace. Later, Channel 4 and Bravo rescreened the films through to the 1990s, later being re-shown on Talking Pictures TV from 2018. It was shown on US television as The Edgar Wallace Mystery Theatre, with episodes cut to fit hour-long commercial TV slots.
In July 2012, Network DVD began to release the complete series on DVD, uncut and presented in its original aspect ratio.
Urge to Kill (1960) and The Malpas Mystery (1960) do not appear to have been part of the original series of films produced at Merton Park. Other films not shot as part of the series, but subsequently included, are Gerry Anderson's Crossroads to Crime (1960)  and Seven Keys (1961).
