With films such as Memento, Eternal Sunshine of the Spotless Mind, and Marjorie Prime exploring the concept of memory and how they seemingly define us. I’d like to suggest a further investigation into the use of memory in film as a narrative tool. How have writers/directors effectively used this device to engage viewers. Are there consistencies within the more successful examples? How could we look to utilise memory as a concept in future films, or even other forms of media.
