La Couchette

Lore & Background

The episode was inspired by the intimacy of sleeper carriages, where people aim to sleep in close proximity to strangers. It draws upon literary tropes associated with stories such as Murder on the Orient Express and Strangers on a Train, following characters unknown to one another while travelling. The various characters correspond to British comedy archetypes, and much of the episode's story and humour derives from the characters' unlikability.

Reader's Guide

"La Couchette" is significant as an example of Inside No. 9's ability to create claustrophobic, character-driven narratives within a single confined setting. Critics responded positively, commending the cast and script, though noting that Inside No. 9 is something of an acquired taste. The episode's legacy lies in its exploration of "man's capacity to behave idiotically within a confined space to creepy and comic effect," and its use of multiple twists and macabre horror typical of Pemberton and Shearsmith's work. The sleeper carriage setting provided traumatic elements such as claustrophobia, proximity to strangers, and motion, which the writers exploited for both humour and tension.

Did You Know?

• The set was shaken manually by an assistant director to create the effect of motion.
• Jack Whitehall suffered from motion sickness on the set and threw up during the first day of filming.
• The episode was filmed by removing walls from the carriage one at a time, requiring the set to be dismantled and reassembled five times.

Setting & Literary Lineage

The sleeper carriage of a French train between Paris and Bourg-Saint-Maurice provides the confined stage for "La Couchette," a premise the writers deliberately chose for its inherent claustrophobia. Reece Shearsmith described the appeal as an "odd frisson" born from the strange intimacy of attempting to sleep in a room full of complete strangers. This conceit places the episode squarely within a well-established literary tradition: the story echoes the dynamics of Murder on the Orient Express and Strangers on a Train, in which a group of mutually unknown passengers are trapped together on a moving vehicle. Rather than a single murder mystery, however, the episode uses the enclosed space to amplify the friction between six very different travellers. The writers exploited the fact that a sleeper carriage forces proximity, vulnerability, and the slow erosion of polite distance, turning a routine overnight journey into a pressure cooker of personality clashes. The setting thus does more than provide a backdrop; it is the engine of both the comedy and the tension.

Production & Filming Challenges

Filmed at Twickenham Studios from late 2014 into early 2015, "La Couchette" presented a uniquely demanding physical production. The carriage set was built on springs so it could rock and shift like a real train compartment, an effect that immediately took its toll on cast member Jack Whitehall, who suffers from severe motion sickness. On his very first day, he had to sprint off the set mid-scene to vomit in the toilet. Director Guillem Morales compensated for the cramped environment by preparing an exhaustive storyboard, ensuring every camera angle was mapped out before a single frame was shot. Because the carriage could only be filmed from one side at a time, the crew physically removed a wall, shot their coverage, then reassembled the structure, repeating this process five times over the course of the shoot. An assistant director manually shook the set to simulate train movement, a detail that surprised actress Julie Hesmondhalgh when she first learned of it. Despite the logistical headaches, the cast embraced the confinement; Mark Benton called the tight space "great" for the performers, and Pemberton recalled it as a "tough week" that was nonetheless "really fun."

Cast & Character Archetypes

The six passengers of "La Couchette" are deliberately drawn from a palette of familiar British comedy types, and much of the episode's humour springs from their collective unlikability rather than from any single joke. Steve Pemberton plays Jorg, a drunk and flatulent German; Reece Shearsmith is Maxwell, an English doctor bound for a major interview; Julie Hesmondhalgh and Mark Benton form Kath and Les, a couple heading to their daughter's wedding; Jessica Gunning is Shona, an Australian backpacker; and Jack Whitehall portrays Hugo, a posh English "trustafarian." Whitehall, a self-proclaimed fan of the series, admitted he "may or may not have nagged" the writers to carve out a role for him, and was "very thankful" when they did. Hesmondhalgh called the part a "no brainer," while Whitehall found the pairing of Benton and Hesmondhalgh "an amazing little double act," noting they had previously played a married couple on radio. He also remarked that working alongside Hesmondhalgh felt "very exciting, but also quite weird" in the wake of her Coronation Street character Hayley Cropper's recent on-screen suicide.

Reception & Audience Response

On its initial broadcast, "La Couchette" drew 1.1 million viewers, capturing 6.1 percent of the audience watching at the time. Critics responded broadly favourably, singling out the performances and the writing as particular strengths of the episode. Pemberton and Shearsmith's script was praised for its sharp character work and the way it sustained comedy through a single, unbroken location. However, several reviewers flagged a recurring caveat about the Inside No. 9 franchise as a whole: it is, in their words, something of an acquired taste. The show's dark, often abrasive humour and its willingness to let its characters remain deeply unlikable can test viewers who prefer more conventional comedy structures. That the episode nonetheless secured a solid audience share on its first airing suggests that the sleeper-carriage conceit and the strong ensemble cast were enough to draw in viewers who might not have gravitated toward the series otherwise. The positive critical consensus, tempered by that note about accessibility, set the tone for the second series and reinforced the show's identity as a niche but devoted favourite within British television.
