25 years later, this twisty psychological thriller still beguiles.
Christopher Nolan’s second film, Memento, celebrates its 25th anniversary this year, and it remains just as inventive and audacious as ever – with its daring use of voiceover still standing as one of the most striking demonstrations of how profoundly VoiceOver can shape narrative cinema.
At the film’s centre is Leonard Shelby (Guy Pearce), a man suffering from short-term memory loss after a brutal attack that killed his wife. Leonard cannot form new memories: after a few minutes, the world resets for him, leaving only scraps of information he has tattooed onto his body, Polaroids scrawled with notes, and fragments of determination. His mission is simple – find his wife’s killer – but his condition ensures it is anything but.
Nolan structures the film to mirror Leonard’s disorientation (and for the un-initiated reader, brace yourselves – this is complex!) The film follows two chronological timelines at the same time. The main storyline runs backwards and in colour, tracing Leonard’s movements up until the second chronology: we begin at the end, and each scene unfolds before the events that precede it. Interposed alongside this is a second, black-and-white chronology that moves forward in time, showing Leonard in a motel room trying to keep track of what happened to his wife. These two narrative strands twist and turn until they collide, meeting in the middle where ‘beginning’ and ‘end’ are one and the same. For viewers, this means certainty is always withheld. We, like Leonard, live inside confusion, trying to assemble fragments into coherence.
The Innovative Sonic Construction
This is where the film’s use of voiceover becomes salient. Leonard’s internal monologue is our lifeline. As he tattoos facts, scribbles notes, and rifles through Polaroids – he audibly explains his methods, his reasoning, his rules for survival. It grants us access to his mind, initially providing the illusion of clarity amidst chaos. But the brilliance of Nolan’s design is that this clarity is treacherous. Leonard is not deliberately lying – he doesn’t know what is true. And we start to question his conclusions, as we rely on his words to guide us. This tension is the heartbeat of Memento. The film isn’t simply about an unreliable narrator – rather it is about a narrator who is unreliable even to himself. Without his constant monologuing – guiding, misguiding, and destabilising – the serpentine chronology would collapse into confusion. With it, Nolan creates a narrative experiment that still twists and beguiles 25 years on.
The brilliance of Memento is that the voiceover is not ornamental. It is not there to fill gaps or smooth over complexity. Instead, it is the very mechanism that allows the film to exist. Without it, Nolan’s intricate structure would risk collapsing into abstraction. With it, the story finds rhythm, coherence, and emotional weight.
Christopher Nolan’s Rationale
Nolan himself described the film’s guiding principle as a desire to “deny the audience the same information that the protagonist is denied.” The monologuing becomes the perfect tool to achieve this. It appears to grant access to Leonard’s thoughts, whilst at the same time withholding the certainty we crave. In the colour sequences, his speech feels intimate and subjective, shaped by Leonard’s faltering grasp of his surroundings. In the black-and-white motel scenes, it begins in a cooler tonal register – observational, detached, almost clinical. Yet, as the dual chronologies move toward convergence, these distinctions begin to collapse. Subjectivity bleeds into objectivity, and what once seemed stable grows increasingly unstable. By the time the timelines meet, his words themselves have dissolved into ambiguity, mirroring the story’s collapse of truth.
This is where the power of the voiceover truly reveals itself. Composer and sound designer David Julyan ensures that it does not merely guide the audience; it sets the pace and the texture of the film. Pauses, hesitations, and emphases become part of the storytelling language, creating rhythm and unease. It even manipulates time, layering Leonard’s fractured commentary over the images in ways that create dissonance and tension. We process what we see whilst simultaneously processing his interpretation, never sure which is more reliable.
What elevates Leonard’s words in Memento from a narrative device to performance art is not just what it tells us, but how it is delivered. Guy Pearce’s performance as Leonard is subtle, understated, and meticulously calibrated – a vocal tightrope walk between clarity and disorientation. Each sentence is measured, each pause carefully placed, creating a rhythm that mirrors Leonard’s fractured cognition.
Ultimately, Guy Pearce’s performance in Memento demonstrates the remarkable capacity of cinema to transform sound into experience. It is not just a way of hearing Leonard’s thoughts – it’s a way of living them, feeling the vertigo of memory loss, the fragility of certainty, and the gnawing drive for meaning in a world that constantly resets. Pearce’s delivery, combined with Nolan’s design, ensures that we do not merely witness Leonard’s journey; we inhabit it. In this sense, the voiceover transcends narration – it becomes the soul of the film, a delicate, haunting and unforgettable conduit for doubt, memory and identity. Even 25 years later, it remains one of the most sophisticated and profoundly affecting voiceover performances in cinema, reminding us that the power of speech is not just in what it tells us, but in how it makes us feel the world as the speaker feels it.
