The secret life of a scream park is a world of fear, fainting, and even 'code brown' incidents, where scare actors learn to target the most reactive victims. At PrimEvil, billed as Norfolk's premier scare attraction, park director Ben Francis trains over 100 actors each year to deliver maximum fright. For about £40 a ticket, groups roam themed attractions like the Circus of Screams, where clowns and special effects push heart rates to the limit.
What Happens Behind the Scenes at a Scream Park?
PrimEvil is months in the making, with dozens of crew and over 100 actors spread across six themed attractions. Each night is a carefully choreographed production drawing on familiar horror tropes—scary clowns, dark mazes, and jump scares. The goal is to create an immersive experience that feels real, even though the risks are minimal.
Francis and his team study group dynamics to maximize scares. They know that teenage boys 'scream like banshees, and run in packs,' while teenage girls tend to be unimpressed and may get nasty if scared too much. Mixed groups often have an alpha male who won't react, so actors are advised to aim for the weaker one at the back.
Why Do People Faint at Scream Parks?
The spikes in heart rate are very real, and some visitors do faint. The intense fear response triggers a fight-or-flight reaction, which can lead to dizziness and loss of consciousness. Scare actors are trained to recognize the signs and call for help if needed.
Fainting is not uncommon in extreme haunted attractions, where sensory overload and adrenaline rushes can overwhelm the body. Parks like PrimEvil have protocols in place to ensure visitor safety, including trained staff and medical support on standby.

What Is a 'Code Brown' at a Scream Park?
A 'code brown' is industry slang for when a visitor is so terrified they lose control of their bowels. It's a rare but memorable event that scare actors and crew handle with professionalism. The term is used discreetly over radios to alert cleaning crews without causing panic.
While it might sound humorous, code brown incidents highlight the extreme psychological impact these attractions can have. Parks prepare for such contingencies with cleaning supplies and private areas for affected guests to recover.

How Do Scare Actors Tailor Their Approach?
Francis shares his demographic insights with new performers each year. Teenage boys are targeted for their loud reactions, while teenage girls require a different tactic—scare and move on quickly. Mixed groups are trickier, as the alpha male may not react, so actors focus on the more vulnerable members.

This psychological profiling is part of the workplace induction at PrimEvil. Actors learn to read body language and group hierarchies to deliver effective scares without crossing the line into genuine distress.
