WHISTLE is a supernatural horror movie now coming to Shudder. It’s a classic teen horror movie with a curse, but it’s much better than I expected. I feel like it got a tough break, but I enjoyed it. Didn’t love the third act, but that final scene was brilliant. Read our full Whistle horror movie review here!

WHISTLE is a horror movie with a supernatural curse plot. Not unlike It Follows or Tarot, but still with its own little twist. A twist I really liked. So much so that I felt it was a breath of fresh air in this horror niche featuring teenagers battling a sinister curse.

Due to many reasons, I never had the chance to watch it when it was out in theaters, and from what I heard, I figured I hadn’t missed out on much. Well, color me pleasantly surprised as this was much better than I expected. Admittedly, I wasn’t thrilled with all the elements of the final act, but I loved that very last scene!

Beware the Aztec Death Whistle

Whistle is the story of a group of teenagers who come across a cursed object. Or rather, it seems the object seeks them out, so this misfit group of unwitting high school students never stood a chance. The cursed object is an ancient Aztec Death Whistle.

And if the name of this object wasn’t enough to get you worried, the effect it has most certainly will.

When someone blows the whistle – which they appear to be drawn, almost mesmerized, into doing – it has an ear-shattering sound. If that were the only thing it emitted, the teenagers would be fine. However, this is a horror movie, so it gets much worse.

Blowing that whistle summons their future deaths to hunt them down now. In essence, whatever the fate of your death, it will come find you within hours or days. As opposed to their fate, which may have been years or even many decades away. It is brutal and extremely smart as far as curses go.

The question quickly becomes: How can they stop it?

Whistle (2025) – Review | Supernatural Horror Movie | Shudder

A very small cast

My one bigger issue with Whistle is the same as the one I had with Tarot Curse – not to be confused with Tarot, which had a bigger budget. These teenagers are running around with seemingly no parents involved in their lives. At all.

Well, there is one exception, but even in that case, we only see them in a brief reaction scene after tragedy has struck. Other than that, the only adult who plays a role in the lives of the High School teenagers is a teacher portrayed by Nick Frost (Shaun of the Dead).

And hey, I am always happy to see Nick Frost, but it just feels strange with no other adults around.

Okay, to be fair, there is one more key adult character. Just like in Tarot Curse, it’s a woman who explains the curse to these kids. In Whistle, she’s portrayed by the wonderful Michelle Fairley (Game of Thrones, How to Get to Heaven from Belfast).

In any case, the teenagers are portrayed by wonderful talent. I enjoyed every single one of their performances. Leading the cast is Dafne Keen (Logan), with Sophie Nélisse (Yellowjackets) ultimately sharing this place.

Also, Sky Yang (Anniversary) is amazing, as are Ali Skovbye (Grizzly Night), Jhaleil Swaby (Chien Blanc), and Percy Hynes White (Wednesday). So, it’s not that there isn’t plenty of talent in this cast, but just that the story feels too thin when we get nothing from their lives apart from their scenes together.

Watch Whistle on VOD or Shudder

Whistle comes from director Corin Hardy, who previously gave us movies like The Nun (yes, The Conjuring spin-off movie) and The Hallow (2015). The screenplay was written by Owen Egerton, who wrote and directed the 2019 horror mystery Mercy Black and the 2015 genre-mix Follow.

On a personal note, I loved that the lead character wasn’t straight (nor was everyone else), and it was treated as a non-issue and just part of the storyline. Kudos to the writer and director for highlighting this in a positive way. Once again, proving that horror is for everyone, even more for anyone not considered “normal”.

With a runtime of 97 minutes, it has a good pace and allows for the story to be character-driven while never forgetting the element of the curse. Speaking of the curse, I felt this was one of the more intelligent approaches to having a teen horror movie with a curse. Not unlike It Follows, which hopefully has a sequel coming soon.

Whistle is streaming on Shudder starting May 8, 2026.

– I write reviews and recaps on Heaven of Horror. And yes, it does happen that I find myself screaming, when watching a good horror movie. I love psychological horror, survival horror and kick-ass women. Also, I have a huge soft spot for a good horror-comedy. Oh yeah, and I absolutely HATE when animals are harmed in movies, so I will immediately think less of any movie, where animals are harmed for entertainment (even if the animals are just really good actors). Fortunately, horror doesn't use this nearly as much as comedy. And people assume horror lovers are the messed up ones. Go figure!
