Beware Boiúna Slithers Into Theatres With Mythic Terror

The Snake That Won’t Show Its Face

Beware Boiúna hits screens with a promise: a mythical Amazonian serpent, Boiúna — also known as Cobra-Grande, decides who lives and who gets swallowed. Mike P. Nelson, fresh off Wrong Turn, directs this jungle horror with a steady hand, but the film’s biggest flaw isn’t the plot. It’s the lack of clarity. Audiences wait nearly the entire runtime for a proper look at the beast. What we get are glimpses: a coiled shadow, a flicker of scales, a tail vanishing into water. It’s frustrating. The camera lingers on tension, not terror.

Jungle Beauty, Creature Gaps

Nick Junkersfeld’s cinematography is stunning. Shots of the river at dusk, mist curling over the canopy, feel like stills from a dream. These moments stop you cold. But they’re undercut by the film’s refusal to let us see what we’re afraid of. Lighting is too low, angles too tight. You squint. You strain. The glittering eyes? Hidden. The massive body? Suggested, never shown.

The cast plays their parts well. Juan Pablo Shuk as Dr Miguel, Jessica Rothe as Alli, Will Close as Callum, each brings nuance to a group already under siege. Then there’s Kiana Madeira as Lena, the mechanic searching for her missing brother, Jorge. Her performance is raw, committed. And Logan Marshall-Green and Jackson Bews as the villainous loggers Brennan and Shawn? They’re the kind of selfish, loud antagonists that make you root for the monster.
