The Similars

The film takes place at a Mexico City bus depot during a stormy October night. This isolated, utilitarian setting serves as both shelter and confinement for the eight characters trapped there. The rain and storm create a sense of dread while physically isolating the depot from the outside world, forcing the characters to confront the strange phenomenon within these cramped, claustrophobic walls.

The bus depot functions as a liminal space, a waiting zone between destinations that becomes a trap. Its utilitarian design with payphones, offices, and loading docks creates an atmosphere of mundane confinement. As the transformations progress, the space itself seems to warp, transforming from a place of temporary passage into a nightmarish chamber where identity dissolves and reality bends.

The film explores how identity erodes when faces and memories blur, with the group beginning to mirror Ulises and forgetting who they originally were. Personal distinctiveness collapses into a shared guise, reshaping social roles and trust. Memory becomes treated as a mutable trait, allowing a collective self to emerge while individuals remain unaware of what they have sacrificed. The theme probes how identity is sustained by perception and social agreement.

Transformation depicts bodies becoming vessels for an external imposition, as characters physically take on Ulises's features. The rapid morphing unsettles alliances and reframes power dynamics within the group. These transformations challenge the line between self and other, forcing characters to question what makes someone human. The motif underscores the film's sense of alien intrusion into ordinary life.

Ignacio possesses reality-altering power, manipulating what the group believes to be true. A comic book about aliens frames the threat as something that can be summoned into existence. His memory wipes and the final reminders show a fragile line between illusion and fact, leaving survivors questioning what they witnessed. The authorities misinterpret events, arresting Alvaro as the catalyst while Ignacio alone retains true memory of what happened.

Ulises is a frustrated miner waiting at the depot with his wife Irene, who is in labor. He becomes the first to display the storm-induced transformations, and his fear and stubbornness drive him to protect his unborn child. As the plot unfolds, his body and identity slowly fuse with others, making him the central catalyst for the identity collapse affecting everyone in the depot.

Ignacio serves as the catalyst with reality-warping powers who prevents the group's departure and literally reshapes the world around them. His entanglement with the aliens and his conscious doubt set the climax's stakes. He alone retains memory of the truth while others have their minds altered, making him both the source of the threat and the only one who truly understands what has happened to the group.

The pregnancy of Irene serves as a focal point of hope and vulnerability amid the identity collapse. Her desperate search for shelter and safety drives much of the early action. The unborn child becomes entangled with the comic book prophecy about aliens, adding conceptual depth to the narrative. The pregnancy represents potential new identity and the ultimate stakes of whether any trace of humanity can survive the transformation.

The film shows individual identity dissolving into a collective existence as characters physically and psychologically merge. The group begins to share a single face and lose track of their original selves. This reflects the theme that identity is sustained by perception and social agreement, when those foundations collapse, individuals become part of a homogeneous whole without recognizing what they've lost. The ending confirms this loss applies to nearly everyone.

A comic book about aliens serves as a frame that makes the supernatural threat feel predestined. It suggests the phenomenon can be summoned into existence, adding a layer of self-fulfilling prophecy to the horror. The prophecy connects to the child, indicating that Ignacio's experiments and the alien incursion were potentially avoidable or intentionally triggered. This element adds conceptual depth to the otherwise contained horror scenario.

The Similars blends body horror with existential dread, focusing on the unstoppable transformation of characters into duplicates of one another. The horror stems from identity annihilation, watching individuals lose what makes them unique while remaining unaware of the loss. The bleak tone, absence of levity, and high tension create psychological unease rather than relying on jump scares or gore.
