The horror internet is in full meltdown mode after the second official trailer for Whalefall dropped. Director Brian Duffield, who previously helmed No One Will Save You, has crafted a premise that is instantly shareable: a man trapped in the belly of a giant sperm whale. We’ve ranked the top five elements of the trailer that are driving the current viral wave.

5. The Cast Stack

Austin Abrams stars as Jay Gardiner, diving off the central coast of California to find his deceased father’s remains. Supporting cast includes Elisabeth Shue, Jane Levy, John Ortiz, and Emily Rudd, with Josh Brolin portraying the father. It is a solid lineup that signals a serious indie-horror project, though the cast is not the main driver of the current buzz.

2. The Star Power

Austin Abrams is also set to star in Zach Cregger’s upcoming Resident Evil, which opens in theaters this September. This dual presence in two high-profile horror projects makes him the face of the current wave, amplifying the viral reach of Whalefall before its release.

1. The One-Hour Oxygen Clock

This is the viral engine. Jay is swallowed by the massive sperm whale and finds himself trapped in its stomach with only one hour of oxygen remaining. The narrative suggests that the advice and lessons he learned from his father will serve as the key to his survival. This ticking-clock mechanic is exactly what makes the trailer clip loop endlessly on social platforms.
