The Serpent’s Call by Jennie Kermode


When a film delves into the mythical, it doesn’t just tell a story—it demands an experience. Mike P Nelson’s Beware Boiúna is a prime example of this cinematic ambition. Opening at Fantastic Fest and currently screening at BeyondFest, the movie promises a journey into the heart of the Amazon Basin, where the line between reality and legend blurs entirely.

The success of such an epic venture hinges on one crucial element: cultivating a genuine sense of awe in the audience. This is a film that asks viewers to suspend their disbelief and embrace the sheer scale of its world.

At its core, Beware Boiúna explores the existence of a legendary creature—a figure viewed by some as a monster, and by others as a god—which local populations believe holds the ultimate power to dictate life and death. It is a profound mythological exploration set against the breathtaking backdrop of the vast Amazon.

But a visual spectacle alone cannot deliver this kind of immersive wonder. For a film rooted in such mythic territory, the score becomes the unseen architect of the emotional experience. This necessity led to an important conversation with composer Stephen Lukach, who shared insights into the critical role sound plays in elevating the narrative.

Lukach discussed the collaborative nature of the creative process, noting that he has previously worked with Mike Nelson on other projects. Their history includes their collaboration on Nelson’s feature film The Domestics.

During that initial collaboration, Lukach worked as an assistant to composer Nathan Barr, which provided a foundational experience for the team. This history demonstrates a shared commitment to weaving complex emotional landscapes through sound.

Ultimately, the magic of Beware Boiúna lies in this synergy—the untamed majesty of the Amazon, the enigmatic nature of its central figure, and the masterful musical composition that wraps the audience in a feeling of profound wonder. It is a testament to how powerful storytelling, paired with exceptional sound design, can transform a narrative into an unforgettable, awe-inspiring cinematic event.
