TL;DR:
The ending of Possession (1981), directed by Andrzej Żuławski, is a surreal and emotionally charged culmination of psychological horror, marital breakdown, and metaphysical dread. The film follows Mark (Sam Neill) and Anna (Isabelle Adjani), whose toxic relationship spirals into madness as Anna becomes entangled with a grotesque, tentacled creature she treats as a lover. In the climax, Mark confronts Anna and the creature, leading to a violent confrontation that ends with Anna killing Mark, the creature's transformation into a doppelgänger of Mark, and a final scene where their son, Bob, destroys their remnants-suggesting cyclical trauma and existential annihilation. The film leaves many questions unanswered, blending body horror with profound existential themes.

Detailed Explanation of the Ending

The finale of Possession is a feverish, nightmarish sequence that solidifies the film's themes of psychological disintegration and metaphysical horror. After Anna's descent into obsession with the monstrous entity (often interpreted as a manifestation of her repressed desires or a Lovecraftian horror), Mark confronts her in the apartment where she has been keeping it. Their relationship, already a battleground of emotional and physical abuse, reaches its breaking point when Anna stabs Mark to death in a frenzied attack. This act of violence is both shocking and inevitable, given the film's relentless escalation of hysteria and despair.

Meanwhile, the creature undergoes a bizarre metamorphosis, transforming into a doppelgänger of Mark-a twisted reflection of the protagonist's fractured identity. This doppelgänger then enters the real world, replacing Mark in a chillingly mundane setting: a school where Anna previously worked. The new "Mark" shoots Anna when she tries to expose him, reinforcing the film's themes of duality, identity collapse, and the impossibility of escaping one's own destructive cycles. The doppelgänger's existence suggests that the horrors of their relationship are not confined to the personal but have infected reality itself.

The final scene shifts to their young son, Bob, who silently witnesses the aftermath of his parents' destruction. In an eerie and symbolic act, Bob uses a toy to "erase" the remnants of his parents' existence, including a photograph of them and the apartment itself. This gesture implies a rejection of the toxic legacy left by Mark and Anna, but it also carries an unsettling ambiguity-does Bob possess supernatural agency, or is this another layer of unreality? The film's closing image of an empty, ruined apartment underscores the total annihilation of the family unit, leaving the audience with a sense of existential unease.

Unresolved Questions & Possible Interpretations

  1. What is the creature?

    • A physical manifestation of Anna's repressed desires or mental illness.
    • A Lovecraftian entity symbolizing the incomprehensible horror of marital dissolution.
    • A metaphor for the "other" in relationships-the unknowable, monstrous aspects of a partner.
  2. Why does the creature transform into Mark's double?

    • It reflects Mark's own monstrous nature, suggesting he and Anna are equally destructive.
    • The doppelgänger represents the inescapability of their toxic dynamic, now externalized into the world.
  3. What does Bob's final act signify?

    • A child's attempt to erase trauma, but with eerie, possibly supernatural implications.
    • A cyclical interpretation: the next generation repeats or destroys the past.
  4. Is any of this real, or is it all psychological?

    • The film blurs reality and hallucination, leaving it open whether the creature is literal or symbolic.

Personal Opinion on the Ending & Film

Possession is a masterpiece of visceral horror and emotional extremity, and its ending is both baffling and unforgettable. The film's unrelenting intensity-bolstered by Isabelle Adjani's volcanic performance-makes the finale feel like the only possible conclusion to such a deranged narrative. The creature's transformation into Mark's double is a stroke of genius, suggesting that the horror of their relationship has transcended the personal and infected reality itself. The ambiguity of Bob's role adds another layer of unease-is he a victim, an avenger, or something more sinister?

While the film's surrealism may frustrate some viewers, its raw exploration of love, madness, and identity makes it a singular work. The ending refuses easy answers, instead opting for a haunting, open-ended collapse that lingers long after the credits roll. It's a film that demands multiple viewings, as its layers of metaphor and nightmare logic reveal new depths each time. Few horror movies capture the terror of emotional annihilation as powerfully as Possession, and its finale remains one of the most disturbing and thought-provoking in cinema history.

In summary, Possession's ending is a culmination of its themes-destruction, duality, and the impossibility of escape. Whether interpreted as psychological breakdown or supernatural horror, it leaves an indelible mark, ensuring the film's place as a cult classic that defies conventional analysis.
