When the Screaming Starts Ratings & Reviews
Kevin Ward
July 12, 2025
I typically love a good mockumentary. This one follows a would-be serial killer (meaning he hasn’t as yet actually murdered anyone) in an attempt to capture a true-crime documentary that is contemporaneous with the crimes themselves. It’s a funny enough premise, but as is typical with comedies, your mileage will vary depending on how much the humor lands with you. Unfortunately, not a whole lot of it landed for me. I could see people having a good time with it. It’s well made and had fitting performances. Worth giving a shot to see if the humor works for you.

As the film vaults to its third act, there's a twist that makes the feature a surefire delight.

When the Screaming Starts is filled with laughs, some genuine scares, and deserves a cult following.
Backseat Mafia
Rob Aldam
A fun and inventive mockumentary which plays with the public's obsession with serial killers.
IGN Movies
Matt Donato
When the Screaming Starts earns its horror-comedy laughs and savors its bleaker commentary on fame-driven obsessions as a sharp serial killer mockumentary.
Dread Central
Sharai Bohannon
When the Screaming Starts is a laugh-out-loud funny dark comedy, and the film breathes a lot of life back into the mockumentary subgenre.
Screen Zealots
Louisa Moore
A clever, distressing serial killer mockumentary that offers a piercing commentary on the world we live in. It's also bloody hilarious.
