Primate is climbing the streaming charts, and here's why the overlooked horror flick is taking the world by storm. 2026 has already been an incredibly crowded year for horror, and Primate is just one of many movies released since January. The animal attack story debuted at festivals back in 2025, but didn't hit theaters until this year. It hearkens back to a simpler time for the genre, which is part of its appeal. The plot concerns a family reunion that is violently interrupted when their ultra-intelligent pet chimpanzee goes on a rampage. It features a cast of relative unknowns, though it is anchored by Oscar winner Troy Kotsur. Instead of featuring real chimps, Primate made the wise decision of bringing the deadly simian to life through practical effects and a stellar physical performance from Miguel Torres Umba. The movie was only a modest success during its theatrical run, mustering about $40 million worldwide against a budget somewhere in the $20 million range. With additional costs factored in, it's unclear if Primate broke even at the box office. Regardless of its financial uncertainty, the movie seemed destined for popularity on streaming. Months later, the film is finally getting its due. Primate has now become a bona fide streaming hit, finding an audience it couldn't when it was in theaters. A number of factors have contributed to its success, and it's the sort of movie that works well with a streaming audience. In the modern movie landscape, a film's success or failure isn't exclusively determined by how well it does in theaters. Why Primate Is Trending On Prime Video This week, Primate has been working its way up the streaming charts, and has cracked the top five on Amazon Prime Video. The film debuted at the seventh spot, but is already gaining ground on the competition. There are several reasons why, not the least of which is the fact that Primate is an old-fashioned horror flick. Those always tend to do well on streaming, especially in a year so hungry for new frights. Another big reason for the movie's sudden success is that this is the first time that Primate has streamed anywhere other than Paramount+. Because it's a Paramount release, it was only natural that the company's signature streamer would get the first crack at Primate. Now that that window is closed, it has been opened to a much larger audience. Perhaps a less obvious reason for Primate's streaming success is its familiarity. Most new horror movies are trying to push the boundaries of the genre, but Primate isn't quite so ambitious. In fact, it bears a striking resemblance to a classic story by Stephen King, and considering his unending popularity, it makes the streaming success of Primate a bit more understandable. Primate Is Perfect For Fans Of Stephen King's Cujo It would be a stretch to say that Primate is a ripoff of Stephen King's Cujo, but they do go well together. They both tell stories of animals contracting rabies and terrorizing unsuspecting people. They both also feature complex family dynamics, which add intrigue to the simplistic animal horror concept. Cujo's story is a bit richer than Primate's, but they make for a strong double feature. Cujo is about the loss of innocence, and how something as loveable as a dog can become vicious. Whereas Primate is a pretty stark warning about the power of nature, and how wild animals remind us about the fragility of humanity. Primate gets an edge in the scare department though, and a rampaging ape is decidedly more frightening than a killer pooch. Not only is Ben more powerful than Cujo, he's smarter too. Nevertheless, Primate feels like something that King himself could have written. It understands the fundamentals of what makes its story scary, and it exploits that fear by placing the characters in an inescapable situation. Stephen King's scariest works do the same, and are an excellent lesson in the craft that goes into horror. Perhaps the biggest reasons that Primate is climbing the streaming charts is because it is a pretty good movie.
