Christopher Nolan’s Memento comments upon and explores the relationship between films and memory; this is most effectively achieved through the film’s unique editing, both how events unfold in reverse order, and by juxtaposing silent, out of context snippets with the scene at hand.
Like any experience, watching a film creates memories. Likewise, these memories are unique for each person; what shape they take depends greatly on the individual’s state of mind, previous experiences, world view, and engagement with the film. After you are finished watching a film, you have a new set of memories, and, again, like all memories, they were triggered by intense emotions. Therefore, the parts of a film you remember will be different than those recollected by your neighbor, because you have responded to certain shots or scenes or musical cues based on how they made you feel, and what existing memories they recalled and are now tied to.
In the case of Memento, for example, if you have ever gotten a tattoo, or you are a tattoo artist or know one, your mind might assign specific emotional significance to Leonard’s tattoos, where as others in the audience who do not share this kind of experience will only treat these inky notes on the body of our protagonist as merely parts of the story. Likewise, if you own the same make and model of the car that Leonard drives, you will more than likely create a memory of the film focusing on this detail, while others will pay it no mind. Technically speaking, you are all watching the same film, but in essence you are not; the film each person remembers will be different, because as it enters the brain it is melted down and blended with a person’s biases, interests, and life experiences to create something completely unique. The filmmakers address this subjectivity directly, when Leonard says, “Memory can change the shape of a room; it can change the color of a car. And memories can be distorted. They're just an interpretation, they're not a record...”
