Whistle

Whistle (2026) is a horror mystery directed by Corin Hardy that you can watch online on iFILM. Dafne Keen and Sophie Nélisse lead a cast of teenagers who dig up an ancient Aztec death whistle on a dare — and one short blow sets something in motion that cannot be undone.

The legend around the artifact is precise: whoever sounds it summons their own death, arriving from the future to hunt them down. The group races to piece together the whistle's history before the clock runs out, while adults played by Michelle Fairley and Nick Frost turn out to know more about the object than they let on. Shot across the US and Ireland by Wild Atlantic Pictures, the film runs 100 minutes and keeps the threat concrete — no vague evil, just a countdown. Stream Whistle (2026) online on iFILM.
