Overview
Invasion of the Mermaids is a bold fantasy-horror thriller set for release in late 2025. The film offers a dark, reimagined version of mermaid mythology—turning legendary sea creatures into apex predators seeking revenge against humanity for centuries of oceanic abuse.
Directed by Jennifer Kent, known for her work on The Babadook, and co-produced by A24 and Legendary Pictures, the film blends ecological horror with gothic fantasy.
Plot Summary
When a massive deep-sea mining operation disrupts the ocean floor, it awakens an ancient mermaid civilization from the darkest ocean trenches. Unlike their folkloric portrayals, these mermaids are highly intelligent, weaponized beings who wage war on coastal regions. Using tidal waves, siren songs, and stormcraft, they aim to reclaim the oceans and punish those who’ve poisoned their world.
The story follows Dr. Elara Voss, a marine biologist, and Marcus Hyde, an ex-Navy commander, as they uncover an ancient prophecy and fight to prevent the complete collapse of coastal civilization.
