Film-making had progressed quickly from simple experimental images in the late 1890s to more complex stories in the years leading up to the war, with directors like Charlie Chaplin and D.W. Griffith taking the camera out of the theatre and introducing camera angles, close-ups, and moving carriages following the action, with editing to combine scenes into longer narratives.
This passage emphasizes the way film responded to the wider cultural modernization of the early 1900s through technology, realism, and emotional involvement. The employment of camera movement and editing registered new conceptions of seeing and experiencing space and time, mirroring the break-throughs in science and psychology. Film therefore became a signifier of modernity, transforming visual entertainment into an influential art form expressive of human complexity and social transformation.
