What Is Colossal About?

The premise of Colossal in 317 words, with nothing given away. The full story and the ending follow below.

In a world where a sudden, inexplicable monster looms over Seoul, the ordinary and the extraordinary collide with a disorienting blend of dark humor and quiet dread. The city’s frantic news cycles and the creature’s bewildering movements create a backdrop that feels both eerily realistic and surreal, hinting at forces far beyond any single person’s control while keeping the focus intimate and human.

At the story’s center is Gloria, a woman whose life is a patchwork of stalled ambitions, lingering regrets, and a habit of drinking to numb the edges of a reality that feels increasingly unmoored. Returning to her childhood home after a painful breakup with Tim, she finds herself thrust back into an environment populated by familiar faces—most notably her old friend Oscar, who now runs a modest bar that becomes a reluctant sanctuary for her wandering thoughts. Their uneasy camaraderie, flavored with sharp wit and lingering resentment, paints a portrait of two people trying to reconcile the past with the present.

As the monster’s chaotic path across Seoul becomes a strange mirror to Gloria’s own movements, a subtle, uncanny link emerges, urging her to question the limits of her influence and the hidden depths of her own agency. The film leans into this mystery with a tone that oscillates between sardonic levity and reflective melancholy, inviting viewers to wonder whether the creature is a literal threat or a metaphor for the internal monsters we each carry.

Amidst the glowing neon of a city trembling under an impossible sky, Gloria stands at a crossroads, forced to confront the weight of her choices and the unsettling power she may possess. The story promises a journey that is as much about finding personal redemption as it is about navigating a world where the impossible feels startlingly close, leaving audiences curious about how far a single person can shape a fate that seems written on a colossal scale.

What Happens in Colossal?

The complete story of Colossal, from the first scene to the last, in 534 words (about 2 minutes). Spoilers throughout. Names in the text link to 3 cast member pages.

Spoilers ahead

The film begins in Seoul, South Korea, where a small girl and her mother enjoy a stroll through a park in search of the girl’s lost doll. In a sudden turn of events, a bolt of lightning strikes, heralding the emergence of a towering monster that wreaks havoc on the city, leaving the girl in sheer terror.

Fast forward 25 years, we find Gloria, played by Anne Hathaway, stumbling home in the early hours, visibly hungover. She attempts to justify her erratic lifestyle to her boyfriend Tim (Dan Stevens), but he’s had enough of her excessive drinking and unemployment, and finally decides to pack her things. Left in disbelief, Gloria is soon joined by friends who arrive to party in the apartment.

Relocating from the city back to her roots in her parents’ old home, Gloria encounters her childhood companion Oscar (Jason Sudeikis). Their reunion leads her to the bar Oscar inherited from his father. At the bar, she also meets Oscar’s friends Garth ([Tim Blake Nelson]) and Joel ([Austin Stowell]). As they reminisce over drinks in a nostalgic part of the bar, tensions arise when Joel attempts to kiss Gloria, only for Oscar to intervene.

After a drunken trek home with an inflatable mattress, Gloria awakens to a call from her sister. A shocking news segment reveals that a monster is once again causing chaos in Seoul, igniting her fear. She tries to reach Tim, but he dismisses her due to her state of inebriation. With Oscar’s support, Gloria finds a job at the bar, receiving a television for her dreary living space, leading to more drinking and late-night adventures.

As Gloria witnesses the monster’s movements on the news, she realizes a shocking connection: the creature mirrors her actions. After testing this bizarre link in the park, where she inadvertently influences the monster’s behavior, she invites Oscar, Garth, and Joel to witness this phenomenon. The implications of their antics lead to disastrous consequences, resulting in massive destruction and loss of life. Burdened by guilt, Gloria attempts to communicate her remorse, reaching out to the people of Seoul with a heartfelt message written in the park.

After a complicated night with Joel, Gloria continues to navigate her troubled relationship with Oscar, battling their longstanding issues and his increasingly hostile behavior influenced by alcohol. During their confrontations, flashes of childhood memories unveil their complex history, turning violent as emotions erupt at the bar one night.

As the situation escalates, Gloria devises a plan to confront Oscar, who has become the robot terrorizing the city. In a gripping showdown that juxtaposes her empowerment against her dependency, Gloria travels to Seoul during an evacuation. Unfazed by the chaos surrounding her, she finds the courage to put an end to Oscar’s rampage, ultimately responding to his aggression with strength.

She triumphantly ejects the robot Oscar from the city, reclaiming her agency at the cost of their relationship. As Gloria walks away from the destruction, the scene shifts to her mourning the weight of the events that transpired. In a poignant conclusion, she enters a small restaurant where she meets a friendly woman behind the counter, ready to share her story as she begins to face her future anew.

Ending explained

How Does Colossal End?

The last act of Colossal and what it means, in 319 words. The ending lands as bittersweet. Big spoilers: read the plot summary first if you have not seen it.

The final act, in full

In the climactic final scene of Colossal, Gloria confronts her former boss, Oscar, who has transformed into a giant robot monster and is wreaking havoc on Seoul. As she arrives in her hometown, her own giant creature appears, and she steps forward to face Oscar in a dramatic showdown. During this confrontation, instead of killing him coldly, Gloria physically lifts him and throws him away, but Oscar, overwhelmed by his rage and sense of power, calls her a “bitch” and screams at her. This outburst reveals that Oscar, who had already committed heinous acts by destroying Seoul, is driven by a need to assert dominance and control, refusing to accept weakness or defeat. His insults and rage underscore his toxic masculinity and his refusal to take responsibility for his actions.

Originally, the scene was meant to end with Gloria simply throwing Oscar aside in a cold, emotionless manner—similar to a Western showdown. However, Anne Hathaway, who played Gloria, felt that this would undermine her character’s empathy and moral struggle. She suggested that Oscar should be given one last chance to show humility and remorse, even if he fails. As a result, the director, Nacho Vigalondo, amended the scene so that Oscar’s final words are hostile rather than submissive, emphasizing his arrogance and inability to accept defeat. This choice made the ending more powerful, showing that Oscar’s destructive nature cannot be redeemed or forgiven.

In the end, Gloria’s act of physically defeating Oscar signifies a symbolic victory over both her abuser and his destructive ideology. Instead of forgiveness, the film concludes with Oscar’s defeat firmly established, highlighting that some evil acts are beyond reconciliation. The scene’s emotional intensity and the characters’ choices reinforce the film’s message about the consequences of unchecked power and toxicity. It’s a tragic but fitting ending, reflecting the idea that true justice sometimes means giving up on redemption and choosing to end the cycle of violence.
