Chapter 1 of Edgar-Hunt provides a brief introduction to auteur theory (see page 16). Within this framework, the director is seen to be the "author" of a film (or should be seen as the author). And as authors, the works of different directors can be distinguished by recurring elements or devices, which may be narrative or visual or in the use of sound (as with Robert Altman, see page 168), any point where a specific choice has to be made about what and how to make a film where those choices can be seen as indicative of a director's body of work.
Memento and Inception were both directed by Christopher Nolan. What markers of his "auteurship" can you find in those films? One interpretation of auteur theory is that only certain directors rise to the level of "author" (this view is implied by the text). Do Memento and Inception work to qualify Nolan as an "auteurist" director? Feel free to discuss his other films, too.
