Christopher Nolan’s (2000) is widely regarded as a modern masterpiece of psychological neo-noir, famous for its unique reverse-chronological structure that mimics the protagonist's memory loss. Core Premise & Themes The film follows Leonard Shelby, a man suffering from anterograde amnesia
The term “Index,” derived from Charles Sanders Peirce’s semiotic triad (Icon, Symbol, Index), refers to a sign that is physically or causally connected to its object (e.g., smoke for fire, a footprint for a foot). In film and photography, the index has traditionally signified the physical trace of light on a photosensitive surface.

The paper explores three registers of the memento-index: the corporeal (tattoos), the photographic (Polaroids), and the digital (data logs). It concludes that in an era of deepfakes and digital manipulation, the indexical authority of the memento is both more desperate and more suspect than ever before. index of memento
