Beware! Boiúna’s images unleash the Amazon monster

A Colossal Predator Awakens: New Horror Feature Beware Boiúna Set for Amazonian Thrills

The curtain is rising on a thrilling new horror epic, Beware Boiúna, directed by Mike P. Nelson and set to unleash the fearsome power of the Brazilian Amazon upon the big screen. Following the success of films like Wrong Turn and Silent Night, Deadly Night, this new creature feature promises a deeply immersive experience for audiences.

Mark your calendars: Beware Boiúna is scheduled to arrive in theaters on October 2, 2026. The anticipation is already building around the newly released first-look images, which offer tantalizing glimpses into the dense jungle setting and the terrifying central conflict.

The film brings together a stellar cast, featuring established talents such as Kiana Madeira, known for her work in films like Fear Street, Jessica Rothe, celebrated for Happy Death Day, and Logan Marshall-Green, who brings gravitas to the role of Brennan Malloy.

The narrative is anchored by screenwriter Alan McElroy, whose portfolio includes critically acclaimed works like Wrong Turn and Halloween 4: The Return of Michael Myers. Together with story contributors Tony Giglio and McElroy, the film delves into a scenario where a desperate medical mission ventures deep into Brazil’s Amazon rainforest along the Curuçá River.

Upon their arrival, the team accidentally awakens Boiúna, a colossal ancient predator and mythical serpent known in Brazilian folklore as the Cobra Grande. This legendary beast, said to inhabit the rivers of the Amazon, is equally deadly on land and water, instantly transforming the humanitarian mission into a brutal fight for survival against nature’s absolute power.

Director Mike P. Nelson expertly guides this high-stakes adventure, pitting a group of young doctors against an ancient force that seeks to reclaim her domain in the heart of the jungle. It is a potent blend of creature horror and intense survival drama.

The production of Beware Boiúna is handled by Constantin Film and JB Pictures, with Robert Kulzer and Jeremy Bolt serving as producers. This collaboration signals a major event in the horror landscape, promising an unforgettable expedition into one of the world’s most exotic and dangerous environments.
