Whalefall: a diver trapped in a sperm whale with sixty minutes of air

Published on June 11, 2026 | Translated from Spanish

Survival cinema dives into deep waters with Whalefall, whose first trailer is now available. The plot follows a diver who, while searching for his father's remains, is swallowed by a 60-ton sperm whale. Trapped in the darkness of the animal's stomach, he has only one hour of oxygen to find a way out before the supply runs out.

60-ton sperm whale swallowing a diver in deep waters, the diver trapped inside the dark and humid stomach of the animal, showing his digital dive watch marking 60 minutes of remaining oxygen, headlamp illuminating organic tissues and valves of his air tank, while desperately searching for an exit, photorealistic cinematic style, dramatic blue-green lighting, viscous and bioluminescent textures, hyperrealistic details of technical diving equipment, sense of claustrophobia and urgency

The technical challenge of filming inside a digital whale 🎬

To recreate the inside of the sperm whale, the team has combined physical sets with computer-generated animation. The lighting was designed to simulate the bioluminescence of plankton and the little light that penetrates through the esophagus. Sound effects were recorded with underwater microphones and mixed with real whale recordings, creating an oppressive atmosphere. The lead actor filmed in a 500,000-liter tank, synchronizing his breathing with the plot's countdown.

The escape plan: more complicated than getting out of rush hour traffic 🐋

Getting out of a sperm whale is not like asking for the check at a restaurant. The protagonist must deal with stomach acids, squid bones, and slow but steady digestion. If he manages to break through, the ending could be worse: being expelled from the other end. The film promises to be a claustrophobic journey where the greatest fear is not drowning, but ending up as part of the daily special.
