Lionsgate has released a trailer for Beware Boiúna, a creature feature based on Brazilian folklore about a colossal, man-eating serpent that dwells in the rivers of the Amazon. Mike P. Nelson (Silent Night, Deadly Night [2025]) directs from a script by Alan McElroy (Halloween 4: The Return of Michael Myers).

Jessica Rothe (Happy Death Day) stars as a hot young physician traveling along the Curuçá River in the Amazon rain forest with a team of hippie doctors on a humanitarian mission. The Boiúna is soon awakened and hunts them down on land and water like the grumpy bitch she is. The film arrives in theaters Oct. 2.
