The Substance (2024) Explained: Themes, Ending, and the Tragic Duality of Self

The Substance (2024), directed by Coralie Fargeat, offers more than just a gruesome visual spectacle. The film explores the themes of identity, self-worth, and the obsession with youth in the entertainment industry. It is a satirical body horror movie that uses grotesque transformations to expose the toxic pursuit of perfection. By the time the film reaches its shocking conclusion, it leaves viewers questioning how far individuals are willing to go in their quest for fame and relevance, even at the cost of self-destruction. In this breakdown, we will explain the film’s deeper themes, dissect its ending, and understand how The Substance serves as a critique of the entertainment industry and society’s expectations of beauty.

The Tragic Conclusion of The Substance: A Reflection on Self-Worth

The ending of The Substance is a devastating commentary on self-worth, particularly in the context of the entertainment industry, where age and appearance are often viewed as commodities. At the core of the film is the mysterious “Substance,” a serum that allows users to create a younger, “perfect” version of themselves. Elisabeth, played by Demi Moore, is a fading celebrity desperate to reclaim her former glory, while her younger counterpart, Sue, represents everything Elisabeth used to be—youthful, beautiful, and adored. The serum allows Elisabeth to switch bodies with Sue every seven days, but the process comes with strict rules, which are eventually ignored, leading to catastrophic consequences.

As the two versions of Elisabeth, Sue and her original self, battle for control, it becomes clear that they see each other as rivals rather than as two halves of the same person. Their growing animosity leads to a final, tragic transformation that reflects their internal conflict. The film’s climax and resolution drive home the point that both women—essentially the same person—are responsible for their own destruction. This isn’t just a film about body horror, but about the horror of losing oneself in the pursuit of an ideal that society imposes.

The Final Transformation: Elisabeth and Sue Become One

The final moments of The Substance see Sue, in her attempt to sever ties with Elisabeth completely, facing a gruesome fate. After killing Elisabeth in a fit of desperation, Sue believes she has finally won the battle for control. However, her victory is short-lived. Without Elisabeth to provide the Stabilizer serum necessary for Sue’s survival, her body rapidly begins to deteriorate. Sue’s desperation leads her to break one of the cardinal rules of the serum: never reuse the Activator. When she tries to use the serum a second time, the resulting transformation is horrifying. Sue does not revert to her youthful form but instead creates a grotesque hybrid of herself and Elisabeth.

This final transformation is one of the most powerful moments in the film, not just for its shocking visuals but for the thematic implications it carries. The hybrid, known as “Monstro Elisasue,” is a physical manifestation of the rivalry between Elisabeth and Sue, a monstrous fusion that represents how their obsession with youth and fame has dehumanized them both. The scene is tragic because it highlights the futility of their pursuit—no matter how hard they try to separate themselves, they are ultimately the same person, bound by the same desires and insecurities. The horror lies not just in the visual transformation but in the realization that they were their own worst enemies all along.

The Melancholy Fate of Sue and Elisabeth

The ending is filled with melancholy, as both Sue and Elisabeth meet tragic ends. After the final transformation, Sue’s body quickly collapses. Despite her desperate attempts to maintain her glamorous façade, she is unable to escape her fate. As her body disintegrates, she tries to seek solace in her former glory, heading to the New Year’s Eve show she had worked so hard to secure. But by the time she arrives, her body has decayed beyond recognition. Her teeth fall out, her fingernails peel away, and she is forced to confront the reality of what she has become.

The film’s portrayal of Sue’s final moments underscores the idea that her pursuit of perfection was doomed from the start. The audience no longer sees her as the flawless star she once was but as a tragic figure, deformed by her own ambition. As she collapses outside the studio, her body reduced to a pile of gore, Elisabeth’s face emerges from the remains, crawling toward her forgotten star on the Hollywood Walk of Fame. This cyclical moment, where Elisabeth literally merges with the star that once represented her success, is a poignant reminder of the fleeting nature of fame. The final image of Elisabeth’s remains being swept away by a floor scrubber the next morning is a sobering depiction of how quickly fame and glory can be erased.

The Significance of Sue’s Decision to Kill Elisabeth

One of the key turning points in The Substance is Sue’s decision to kill Elisabeth. Throughout the film, Elisabeth and Sue wrestle for control of their shared life, with Sue increasingly seeing Elisabeth as an obstacle to her success. This tension builds until it culminates in Sue’s final, fatal act: killing Elisabeth to take full control of her life. However, this decision is not as empowering as Sue expects. Instead of freeing her, it leads to her undoing. Without Elisabeth, Sue’s body cannot sustain itself, and she rapidly falls apart.

Thematically, this moment is critical because it highlights how much Elisabeth (and by extension, Sue) has lost touch with her true self. Sue’s decision to kill Elisabeth is symbolic of the way she has allowed her younger self to overshadow her real identity. In the pursuit of fame and beauty, Elisabeth has become so consumed by the image of Sue that she no longer values her own life. By killing Elisabeth, Sue essentially destroys herself. The film makes it clear that their self-destruction was inevitable, driven by their mutual refusal to accept the reality of who they were.

The Unanswered Mystery: Who Is Behind the Substance?

One of the most intriguing aspects of The Substance is the mystery surrounding the origin of the serum itself. Throughout the film, the organization behind the serum remains largely unseen and undefined. Elisabeth first learns about the serum from an unnamed nurse she encounters in the hospital, and her interactions with the company are limited to anonymous phone calls and messages. The serum is delivered to her through a dead drop in downtown Los Angeles, and she never meets anyone associated with its creation.

This lack of clarity adds to the film’s unsettling atmosphere. The organization is not positioned as the villain of the story, but rather as an indifferent entity, merely providing the means for Elisabeth and Sue’s self-destruction. In many ways, the organization’s anonymity reinforces the film’s themes of personal responsibility and self-destruction. The serum is merely a tool; it is Elisabeth and Sue’s decisions that lead to their downfall. By leaving the identity of the organization ambiguous, The Substance places the focus squarely on its protagonists and their choices, rather than on some external force driving their actions.

Harvey: A Symbol of the Entertainment Industry’s Exploitation

While Elisabeth and Sue’s story is central to The Substance, the character of Harvey, played by Dennis Quaid, represents a crucial aspect of the film’s critique of the entertainment industry. Harvey is introduced as the slimy producer behind Elisabeth’s aerobics show, Pump It Up, and it is his decision to fire Elisabeth that sets the events of the film in motion. Harvey is a caricature of the misogynistic forces at play in Hollywood—an older man who dismisses Elisabeth’s decades of success simply because of her age. His callous attitude reflects the industry’s treatment of women, particularly those who are no longer considered young or beautiful enough to be marketable.

Despite his role in Elisabeth’s downfall, Harvey faces no real consequences for his actions. He continues to thrive in his career, enjoying the success that Sue brings to Pump It Up, even as Elisabeth and Sue destroy themselves in their pursuit of fame. The lack of justice for Harvey is a bitter reminder of the predatory nature of the industry, where the powerful exploit the vulnerable and face no repercussions for their actions. The film’s portrayal of Harvey, alongside the lack of consequences for his behavior, serves as a stark commentary on the entertainment industry’s treatment of women and the pressures it places on them to maintain their youth and beauty.

The Themes of Identity and Self-Destruction

At its core, The Substance is a film about identity and the ways in which people can become their own worst enemies. Elisabeth’s journey from a once-beloved star to a deformed shell of herself is a metaphor for the internal battle she faces as she struggles to reconcile her true self with the image of perfection that Sue represents. As the film progresses, the divide between Elisabeth and Sue grows wider, with both versions of herself competing for control of their shared life. This conflict ultimately leads to their mutual destruction, as neither is able to accept the reality of who they are.

The film’s exploration of self-destruction is particularly poignant in its portrayal of how societal expectations can drive individuals to extreme lengths in the pursuit of perfection. Elisabeth’s reliance on The Substance is a reflection of the pressures placed on women in the entertainment industry to remain young and beautiful, even at the cost of their health and well-being. The film’s body horror elements serve as a physical manifestation of the emotional and psychological toll these pressures take on Elisabeth, as her body literally falls apart in her pursuit of an unattainable ideal.

The Tragic Meaning of The Substance

Ultimately, the message of The Substance is a tragic one. The film highlights how individuals, particularly women in the entertainment industry, are often driven to destroy themselves in their pursuit of fame and relevance. Elisabeth’s journey is one of self-doubt, insecurity, and the desperate desire to be seen as beautiful and worthy in a world that constantly devalues her because of her age. The film’s ending, with Elisabeth’s face merging with her Hollywood star, serves as a poignant reminder of how fleeting fame can be and how easily it can be erased.

The real tragedy of The Substance is that Elisabeth’s downfall was not caused by external forces but by her own inability to accept herself. In her quest to reclaim her youth and beauty, she lost sight of her true worth, allowing Sue to overshadow her and eventually destroy her. The film’s use of body horror to depict this internal struggle adds a layer of complexity to the narrative, making it a powerful commentary on the dangers of chasing perfection.
