Another chilling legend awaits everyone to discover and verify: the "Aztec Death Whistle," an ancient artifact from Aztec mythology said to have been used in rituals, producing a horrifying scream that suggests it is no ordinary whistle.
This legend serves as the main inspiration for the new horror film "WHISTLE: The Death Whistle," whose full trailer has just been released to awaken all your senses to the "sound that should never be heard." The story passed down says there is a sound no one should ever hear, because once it sounds, it signals death…and no one survives.
The full trailer reveals clues about the summoning sound that slowly creeps closer with every breath, creating a suspenseful atmosphere from start to finish, turning the "whistle" into a forbidden object that viewers may no longer dare to touch.
The film's peak horror is guaranteed by director Corin Hardy, who previously terrified audiences with The Nun. This time, he returns with the production team behind the horror films Longlegs and The Monkey to raise the terror to a new level, along with a cast of top actors.
Countdown to the ultimate legendary horror awaits with "WHISTLE: The Death Whistle," ready for you to uncover the truth together on 19 Feb 2026 GMT+7 in theaters.
