“Just hanging out in the jungle with a giant snake.” 🐍 She’s almost here! Lionsgate debuted another super scary official trailer for the horror movie Beware Boiúna, a survival thriller about a prehistoric snake in the rain forest, made by filmmaker Mike P. Nelson. A big snake movie just like Anaconda, but even scarier! Reviews are good for this one. Though they’re describing it as a “colossal ancient predator” instead of just a snake. A team of doctors embark on a local mission in the Amazon rain forest, but it soon becomes clear that not everybody – or everything – is happy to see them. Their appearance draws the attention of an ancient predator, the “Boiúna.” In the jungle where nature holds absolute power, she decides who lives & who dies. Beware Boiúna stars Kiana Madeira, Jessica Rothe, & Logan Marshall-Green. This lands in theaters in October just in time for the horror season. It looks like it will scare the crap out of everyone! Watch out.
Here’s the second trailer (+ poster) for Mike P. Nelson’s horror film Beware Boiúna, from YouTube:
