‘I definitely needed a lie-down after that!’ The most nerve-wracking television episodes of all time

Spooks – I Spy Apocalypse from 2003

The episode begins with the intelligence unit restricted while undergoing a drill concerning a fictional terrorist event, overseen by two Home Office officials. As events unfold, it seems an actual attack has occurred and a chemical weapon has been unleashed. The anxiety increases as incoming communications show a disaster happening externally, and escalates as the boss appears to be infected, with the two officials trying to exit, pushing the protagonist portrayed by Matthew Macfadyen to choose between firing at them or permitting their exit and risking contaminating the sealed MI5 offices. This being Spooks, his decision is predictable.

Threads from 1984

Threads was low budget yet among the scariest shows I have ever watched due to its harsh realism and dismal official figures. Viewed it recently following the initial broadcast; I used to visit the pub in Sheffield shown in the series which emphasised the reality and the glib matter-of-fact official information that were transmitted. Remaining completely frightening decades on.

The 2022 Severance episode The We We Are

The concluding episode of Severance’s debut season ranks highly among intense episodes. I was throughout the episode quite literally on the edge of my seat, straining every sinew with Dylan to keep his hands on the levers that allowed the Innies to remain active, while screaming at the Innies to get their truths out there. The concluding高潮 – “she survives!” – felt like an explosion.

The 2024 Industry episode White Mischief

Installment five in Industry’s third series had my heart racing. I needed to stop and stand and exit the space repeatedly due to the immense extent of the wanton self-destruction I observed. Rishi Ramdani is in major difficulty professionally and personally – up to his eyeballs in debt to loan sharks due to his addictive betting, taking such risks with a bet on sterling which may result in huge losses for his employer. Inevitably, he starts a gaming binge, consumes excessive substances and alcohol and wins, loses, wins, gets beaten to a pulp. Each instance you believe things cannot decline more, it does. There is a chance for salvation at the end of the episode yet he wastes the chance, with horrifying consequences during the season’s final episode. Certainly required a rest afterward!

Peep Show – Holiday from 2007

The series Peep Show isn’t typically anxiety-inducing. But the episode Holiday features such degrees of awkwardness that it’ll have you standing up for the full show, filled with nervousness. The situation intensifies when Jeremy and Mark realize needing to deceive regarding the dog they accidentally run over and later efforts to get rid of it. You then occupy the remainder of the episode questioning whether it truly can be worse than incineration, and it turns out to be!

The West Wing – The Two Cathedrals from 2001

Nothing I have seen has been as tense than the first time I watched the second season finale of The West Wing. The show opens with the fallout of the death (in a traffic accident) of the president’s confidential aide and reaches a crescendo with a crisis in Haiti, and the fallout from the non-disclosure regarding the president’s multiple sclerosis diagnosis, with confirmation of his intention to run for another term. Superb programming. Unequaled.

Bodyguard – episode one from 2018

The opening of the British series Bodyguard, featuring the main character on a train accompanied by his small son, is personally a top tense installment. He notices a Muslim female heading to the toilet and knows something is off. The explosive disposal specialists are summoned, enter the train, and endeavor to coax the woman to remove her explosive vest. Suspense rises to an almost unbearable degree, until yes, the vest is diffused.

Buffy the Vampire Slayer – The Body from 2001

Buffy enters her house to discover her mother has died from natural reasons, which is the least common kind of passing in this supernatural show. The episode has no background music, a sullen tone, and we view the installment through the lens of Buffy’s astonishment upon finding her mother.

The 2007 The Sopranos finale Made in America

The concluding moment of the last installment of the program was incredibly anxious. And if you watched it when it originally aired, you – initially – were uncertain of the reason. Tony’s foes, genuine and fictional, had all been defeated. Surely this has the feel of the season one ending? “Remember the little things.” But the mood is bizarrely ominous. Almost Twin Peaks levels of terror. The clan sits in an eatery. Meadow stops the car. Tony gloomily informs Carmela difficulties are arising with an additional associate collaborating with the authorities. Meadow secures a parking space. Odd persons arrive at the eatery. Stare at Tony(?) Meadow is parking. Tony puts a record on the jukebox. Meadow parks her car. The bell sounds, an individual enters. It isn’t Meadow, she remains parking. Tony glances upward. Keep going. It ceases. My heart dropped from my mouth roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I kept late hours to see this show during the night. It was so intense after the establishment of antagonist Negan discovering the characters, savagely teasing his prey then not knowing who he killed (concluded with a suspenseful moment). The point-of-view shot from the victim and the muted audio – ugh! {We then had to wait for season seven|We then needed to await season
