Slaughter also staged other types of production such as the annual Christmas pantomime, where he cast prominent local personalities in bit parts for audience recognition.
He played the young hero in The Face at the Window, poacher Tom Robinson in "It's Never Too Late To Mend", and village idiot Tim Winterbottom in Maria Marten.
Silent footage exists of Slaughter acting on stage at the Elephant and Castle in the military melodrama The Flag Lieutenant, in a documentary entitled London After Dark.
[2] It is said he briefly retired from acting to become a chicken farmer at the start of the 1930s, but it proved a short-lived venture and he was soon back managing his company, touring the provinces and outlying London theatres with a repertoire of Victorian melodramas.
When Slaughter comes on, he favours the audience with a cold, evil grin as the on-stage announcer says "Squire Corder, Lord of the Manor...and a villain!
Slaughter's next film role was as Sweeney Todd in Sweeney Todd: The Demon Barber of Fleet Street (1936), directed and produced by George King, whose partnership with Slaughter was continued in the subsequent shockers: The Crimes of Stephen Hawke (1936); It's Never Too Late To Mend (1937); The Ticket of Leave Man (1938); The Face at the Window (1939) and Crimes at the Dark House (1940).
Many such were forgettable, low-quality films, but the lack of studio interest paradoxically made for quality in one way: it gave the maker, by default, artistic control over the final product.
Slaughter was busy on stage during World War II, performing Jack the Ripper, Landru and Dr Jekyll and Mr Hyde.
After the war Slaughter resumed melodramatic roles on screen and starred in The Curse of the Wraydons (1946), in which Bruce Seton played the legendary Victorian bogeyman Spring-Heeled Jack, and The Greed of William Hart (1948) based on the murderous career of Burke and Hare.
