This thesis examines how the concept of an auteur (author of a film) has developed within contemporary Hollywood and popular culture. Building on concepts from Timothy Corrigan, this thesis adapts the ideas of the author and the commercial auteur to examine how director Christopher Nolan's name, and film work, has become branded as "realist" by the Hollywood film industry and by Nolan's consistent self-promotion. Through recurring signatures of "realism," such as, cinematic realism (immersive filmic techniques), technical realism (practical effects and actual locations), subjective realism (spectator access to a character's point of view), psychological realism (relatable motivations) and scientific realism (factual science), Nolan's work has become a recognizable and commoditized brand. Like many modern-day auteurs, Nolan himself has been used as a commodity to generate interest to his working methods and to appeal audiences to his studio films. Analyzing each of Christopher Nolan's films along with the industrial and cultural factors surrounding them, a method for understanding contemporary auteurism in Hollywood is presented. Through a consideration of extra-textual components, including promotional featurette's and journalistic interviews with Nolan, as well as his film crew, this thesis will explore how Nolan might be considered a template for a future of auteur branding.
