The Knock Knock Man (2025) Review: An Urban Legend Comes Knocking in Indie Horror
Joseph Mazzaferro's supernatural horror feature taps into old-school slasher influences, creepy folklore and practical effects for a brisk trip into the darker corners of independent filmmaking.

There's something about urban legends that makes them such fertile ground for horror movies. Most of us grew up hearing stories about Bloody Mary, mysterious figures lurking in the darkness, or some terrible thing that might happen if we repeated a certain phrase enough times. Naturally, someone eventually gets curious enough to try it.
In The Knock Knock Man, writer-director Joseph Mazzaferro takes that familiar curiosity and builds a supernatural slasher around a mysterious entity that probably deserves a little more respect than your average party game.
At around 73 minutes, the film unfolds at a comfortable, if occasionally slower pace, featuring a memorable antagonist and offering a few delightfully gruesome moments. It’s a modest indie production that knows the charm of a good monster, especially one with his own set of rules.
A Game You Probably Shouldn't Play
The premise follows a group of friends who decide to test an urban legend surrounding a mysterious figure known as the Knock Knock Man. What begins as an innocent dare quickly takes a disturbing turn when someone breaks one of the game's rules, allowing the entity to enter their world.
From there, the friends find themselves facing something far more dangerous than an old campfire story.
There's a familiar supernatural framework at work here. The idea of summoning something through a ritual or game reminded me a little of Talk to Me (2022), where curiosity and peer pressure open the door to forces the characters barely understand. Mazzaferro approaches that concept through the lens of a more traditional supernatural slasher.
I also caught some definite A Nightmare on Elm Street influences throughout the film. As someone who grew up during the 1980s, I can appreciate that. Seriously, how many of us horror kids made it through that decade without Freddy Krueger leaving a permanent impression somewhere in our creative DNA?
The Knock Knock Man himself feels comfortably at home in that tradition of supernatural killers who operate according to their own peculiar mythology.
Atmosphere, Practical Effects and a Creepy Visitor
One of the things I appreciated about the film was its visual presentation. The lighting and cinematography give the production a polished appearance in several sequences, and the filmmakers clearly put some thought into creating an atmosphere that works with the material.
The creature design is another highlight. The Knock Knock Man has an unsettling appearance, complete with a distinctive hat and enough personality to make his presence interesting whenever he arrives. A recognizable monster can go a long way in a horror film, and I think the filmmakers have something worth exploring with this character.
The practical effects also deserve some recognition. There are a handful of kills that benefit from the physicality of practical gore, something I've always appreciated in low-budget horror. The effects give those moments some welcome impact.
I also enjoyed the film's opening 911 call. I won't spoil what happens, although it caught my attention right away and helped establish the kind of experience the filmmakers were aiming to deliver.
The music deserves a mention as well. The score complements the tension and creepy atmosphere throughout the film, supporting the suspense without overwhelming the action. Horror relies heavily on the relationship between sound and image, and I appreciated how those elements came together here.
Familiar Territory With Some Personality
The Knock Knock Man follows a fairly recognizable horror formula. We've seen groups of friends make questionable decisions, investigate supernatural legends and discover the consequences of ignoring warnings in countless genre films.
The characters and story largely serve that familiar setup, and I would have enjoyed a little more development surrounding some of the personalities and the mythology itself.
Still, there's room for filmmakers to revisit familiar territory and introduce their own characters into the genre's growing collection of monsters.
What interested me most was the Knock Knock Man himself. There's a strange personality to the character that occasionally extends beyond the usual supernatural killer routine. His behavior and the rules surrounding his appearances give the story some entertaining possibilities.
I particularly enjoyed the way the film concludes. Without giving anything away, the closing moments deliver a playful little reminder that dealing with supernatural entities can get complicated, especially when you think you've figured out the rules.
The final sequence left me smiling. There's something satisfying about a horror movie finding one last opportunity to get under your skin before the credits roll.
An '80s Horror Kid Behind the Camera
Those old-school horror influences are very much intentional. Mazzaferro, an independent filmmaker based in the Tampa Bay area of Florida, grew up during the explosion of slasher cinema and credits that era with inspiring his creative career.
In comments shared with More Horror, he explained what drew him to this particular project:
"I'm an '80s kid, and I grew up during what I consider one of the greatest eras of horror filmmaking. Slasher movies were a huge part of my childhood, and that fascination never really went away. Those films are a big reason I became a filmmaker. With The Knock Knock Man, I wanted to tap into that same feeling I remember growing up — the suspense, the fear, and the excitement of watching something that genuinely gets under your skin. For me, making horror films has always been about sharing that experience with a new generation of fans."
That makes sense when you consider the film's approach to its central antagonist. The character belongs to a long tradition of supernatural figures who thrive on recognizable imagery, mysterious rules and the terrifying consequences of crossing them.
There's also something rather fitting about a filmmaker who grew up watching Freddy Krueger and his contemporaries now creating his own nightmare figure for another generation of horror fans.
Whether the Knock Knock Man eventually develops into a recurring franchise character remains to be seen, but I appreciate the attempt to contribute another monster to the genre's mythology.
The Independent Horror Factor
I've spent years working on independent films, including productions where budgets were small, schedules were tight and everyone involved had to find creative ways to make things happen.
That experience has given me a particular appreciation for filmmakers who take an idea and actually get it onto the screen.
Putting together a feature-length movie requires an enormous amount of coordination. Finding capable actors, securing locations, getting the lighting right, recording usable audio, creating practical effects and assembling everything into a finished film can become a small miracle of logistics.
And that's before anyone has to figure out how to get people to watch it.
Mazzaferro knows that world well. He founded MAZZ Appeal Films, an independent production company with more than two decades of experience across film and video production.
His body of work spans horror features, documentaries, commercials and other projects. Among the company's horror productions are Halloween at Aunt Ethel's, Scathing, The Haunting of Julia Fields, The House on Laura Anne Dr. and The Box in the Attic.
It's a catalog that speaks to a filmmaker who keeps creating and finding ways to get those projects in front of audiences.
Watching The Knock Knock Man, I found myself appreciating several of those production elements. The visuals work, the practical effects provide some memorable moments, the music supports the atmosphere, and the film keeps its runtime lean enough to maintain momentum.
Of course, there are areas where the film could have benefited from additional development. The story relies on established genre conventions, and some of the characters could use more depth. Those observations are part of discussing the film as a finished creative work.
I also recognize the enthusiasm and commitment that go into bringing a project like this to life.
Independent horror has always thrived on people who love the genre enough to create something with the resources they have. Some of those films eventually become underground favorites. Others find smaller audiences who appreciate them for their creatures, practical effects, atmosphere or wonderfully strange ideas.
You never quite know what might connect with someone.
Final Thoughts
The Knock Knock Man is a decent little independent horror feature with an appealing supernatural premise, some effective practical gore and a villain who has the potential to develop into something even more interesting.
I enjoyed the creature design, the opening sequence and especially the film's closing moments. The production also deserves recognition for its visual presentation and atmospheric music.
It's familiar territory, and the story could have explored its characters and mythology further. At the same time, there's enough here to make it worth checking out for fans of low-budget supernatural slashers and urban legend horror.
I always encourage horror fans to spend some time exploring the independent side of the genre. There's an entire underground of filmmakers bringing their visions to life, often with a fraction of the resources available to larger productions.
Give these movies a chance. You might discover something that earns a permanent spot in your underground horror rotation.
And if someone knocks on your door late at night? Well, after watching this one, you might want to think about your next move.
More Horror Verdict: A respectable indie supernatural slasher with creepy creature design, practical effects and an entertaining final sting. Worth a look for fans of underground horror.
