Beware Boiúna is an upcoming 2026 American action–horror creature feature directed by Mike P. Nelson, who co-wrote the screenplay with Alan B. McElroy and Tony Giglio. The film stars Kiana Madeira, Jessica Rothe, and Logan Marshall-Green.
Set deep in Brazil’s Amazon rainforest, the story follows a group of young doctors on a humanitarian medical mission along the Curuçá River. Their arrival disturbs the territory of the Boiúna, a legendary giant serpent from Brazilian folklore, forcing the group into a brutal fight for survival against a predator that can attack both on land and in the water.
Produced by Constantin Film and JB Pictures, the movie is scheduled for a theatrical release on October 2, 2026. The film blends creature-feature thrills with survival horror and is expected to deliver a tense, bloody, and frightening experience.
Beware Boiúna Age Rating
Beware Boiúna is officially rated R by the Motion Picture Association for bloody violent content, some grisly images, and language. The rating reflects graphic creature attacks, heavy bloodshed, disturbing injury detail, and frequent strong profanity. Although the premise involves a humanitarian mission, the film is designed as an intense horror thriller rather than a family adventure.
Violence & Peril
Violence is strong and graphic throughout. Expect frequent attack sequences involving the giant serpent, with characters being bitten, crushed, dragged, or killed. The film reportedly includes heavy blood splatter, grisly injury detail, and disturbing visual imagery associated with creature-horror movies.
The survival setting adds constant danger. Jungle and river encounters create sustained tension, panic, and a high body count, with little relief from the threat.
Language
The dialogue contains frequent strong profanity, including repeated use of the F-word and other coarse language common in R-rated horror films. The language is used during arguments, panic situations, and survival scenes.
Mature Themes
The movie includes themes of death, fear, survival, and human vulnerability in an unforgiving environment. While the available information does not indicate significant sexual content, the overall tone is intense and emotionally stressful. Characters face traumatic situations, and the film is expected to emphasize terror and desperation rather than humor or adventure.
Is Beware Boiúna Suitable for Teens?
Ages 10–13: No. This film is not appropriate for children or young teens. The graphic violence, gore, and frightening creature attacks are likely to be overwhelming.
Ages 14–16: Generally No. Most teens in this age group will still find the film very intense. The combination of bloody violence, grisly imagery, strong language, and sustained suspense makes it unsuitable for many younger viewers.
Ages 17+: Yes, for horror fans. Older teens who regularly watch R-rated horror and creature features may be able to handle the content. Parents should still expect strong gore and intense suspense.
Overall, Beware Boiúna is best recommended for mature viewers ages 17 and up.
