Special Report: Beware Boiúna (2026)

"What if Sorcerer was a creature feature?" That question is what unlocked Beware Boiúna for director Mike P. Nelson, who tells Mike White how William Friedkin's doomed-expedition structure — immerse the audience in an environment, let it become a character, then release the beast — became his blueprint after he initially turned down a "giant snake movie" pitch from producers Jeremy Bolt and Robert Kulzer.

Nelson details the real jungle: flooded sets, a tarantula bite, a broken bone, and a shoot on a moving river boat that rewrote the schedule daily, plus the VFX philosophy of showing the title creature only through the narrowest slivers of frame so her scale registers even half-glimpsed. Stars Jessica Rothe (Alli) and Kiana Madeira (Lena) join for a separate conversation about shooting on the actual Amazon River instead of faking it on a soundstage, the poisonous dart frog that turned up on a cast chair, the snake wrangler who cleared every space before a take, and finally seeing the finished film with an audience at Fantastic Fest.
