The 1930s was the golden age of the quota quickie, when Teddington was churning out quickly and cheaply shot films by the week, so work was plentiful.
Films on which Williams worked included three early Michael Powell ventures Something Always Happens, The Girl in the Crowd and Someday, of which only the first is still extant.
The quota quickie, (Cinematograph Films Act 1927), assembly line died with the outbreak of World War II, when Britain's major studios started to concentrate on making fewer pictures with higher production values and quality, often with an overtly patriotic and propagandistic tone.
Williams made two forays into film directing, with the 1947 Phyllis Calvert melodrama The Root of All Evil and I'm a Stranger (1952), a comedy starring Greta Gynt.
He spent the rest of his film career mainly in the 1950s B-movie fields of thrillers and crime, with his last credits coming in two Lance Comfort productions in 1961 and 1962.
