Even though D.W. Griffith led the pack in quantity of invasion-call-rescue films, the pinnacle of development of the form during that period came from this lesser-known crew. With its stark title and startling visuals, more realistic characters, less reliance on explicit narrative and instead favoring more subtle story-telling, this bears less resemblance to its contemporaries than to the films that would later be created by Hitchcock (known as 'The Master Of Suspense').
