Innovations in the cinema world are often of great importance, and frequently advanced in the biz to make for a better quality and a more thrilling experience at the show. King Kong is famous for developing a thematic music score, instead of the previously used background music. Max Steiner, a young and aspiring composer at the time, is often held responsible for this new musical addition. Along with music, the movie contained what is stop motion, thanks to "Chief Technician" on the set, Willis O'Brien. The use of stop motion allowed for a life-like animated main character, prior to the addition of CGI animation.
The blending of live action and character animation by means of stop motion and a musical accompaniment that corresponds to the action of a film was considered revolutionary and was used for many years before the invention of computer animation. These innovations broke ground for what was the present technology in cinema, and laid down the bricks for the cinematic road.
