John Slater on AllMovie

Cockney character actor John Slater entered films in 1941, remaining active until his death 34 years later, despite such setbacks as a life-threatening auto accident in 1946 and sporadic bouts of ill health. He could usually be seen as military officers, constables, and doctors. His voice was familiar to millions of moviegoers via his narration duties in the Mining Review documentary series. John Slater's later credits included a lengthy run as Sgt. Stone on the enormously popular TV weekly Z Cars.
