"Bloody hell" is the most British reaction possible to a nuclear explosion

@yaboidapperbot4193

The scariest part is, when you watch a horror film you know that isn't going to happen to you, but this is something that could actually happen.

@Diskoboy1974

Kudos to the sound guy in this film. He did an incredible job on the background noise during this entire portion of the movie. The screaming crowds. The dogs barking. The winds of the infernos. It sounds so genuine and that makes the scene all the more frightening.

@roadkillanonymous4807

This is truly scary.  No gimmicks, no jump scares, monsters, over the top villains, but the actual worst case scenario dangling over our heads that we really do live with.

@scotcarr3390

The really scary thought is that, as bad as this looks, the true nightmare is for the folks who aren't killed outright.

I don’t know what is more disturbing; the guy saying “Jesus Christ, they’ve done it”, the woman who pissed herself, the cold tone that the computer text had or the eerie silence before the wave hit.

This is the live action of what everyone else was doing in 'When The Wind Blows"

@ladysilverwynde

As a child of the 1980s, this hits hard. I was so terrified that this would actually happen in my childhood.

@midnitest0rm

It’s scary because it feels so real. The people panicking. The lady pissing herself. The sirens. The screaming. Terrifying.

@Scufflegrit

Not a horror film. 
An existential terror film.
A warning and a reminder.

@Brytons_Thoughts

The fact that this happens because of a geopolitical conflict involving Iran is a bit chilling right now.

@DavidEllisonReverefilms

'Jesus Christ, they've done..., they've done it.'
Still sends a chill down my spine.

Some of the most realistic scenarios of this scene: 

1) The way people run around aimlessly in terror. They know they need to get away from impending danger but they also know there is nowhere to run to 

2) A woman "wetting" themself from fear. Whether you would think it or not, if you are in enough dread, often your body's automatic response would be to urinate as it is a way for the body to release tension. 

3) Staring at the cause of the destruction - in this case, the mushroom cloud from the bomb - and being frozen in place, unable to move. This can happen with natural disasters, too, such as Tsunamis and Avalanches 

4) Loss of communications in the city and other areas 

5) The white light - a trademark of an Atomic Blast, whenever a Nuclear Bomb explodes a White Light is the first thing those in or near the blast radius witness. It is so bright that people have claimed they could see the bones under their skin, like they were being scanned by an X-Ray machine 

6) Items, buildings, and even the clothes on people's backs spontaneously combust from the intense heat of the blast (around 3000-4000 degrees Celsius). 
Survivors of Nagasaki and Hiroshima also reported that the blast from the bombs dropped in WW2 caused victims' skin to melt off their bodies. 

7) Silence before the sound of the explosion.

@coldwar1977

I was 10 years old when I watched this. No single horror flick traumatized me like this drama did

@kevindenyer428

I never realised until now rewatching this how they got the bombs right and how the effects were before their time.
You see the detonation before the sound because of the distance.
Most depictions have the sound with the detonation.

My boss would be like “your still coming to work this morning right?”

@sixteenstringjack

My childhood is forever divided into: before watching Threads and after.

@RepellentJeff

“Nuclear exchanges escalate.”

I challenge anyone to find a sentence that is more terrifying than that.

@dianealbrecht496

It makes WWII  look like a minor civil unrest.
