Before the Theme Tune: Ten British Cold Opens That Grabbed You by the Collar

There's a very specific kind of telly confidence in starting with nothing. No credits, no jaunty title card, no cast list scrolling past a drone shot of the Thames. Just a room, a face, a line — and about ninety seconds to stop you scrolling.

The cold open (or the teaser, if you're being fancy) is British telly's quiet superpower. American networks use it to shout at you before the adverts. British shows use it to set a tone, plant a question, or simply prove they know exactly what they are. And when it lands, you're in before the theme tune has finished its first bar.

Here are ten that landed.

What actually makes a cold open work

It isn't budget. It's almost never budget. The best ones do three things in under two minutes: they tell you what kind of show you've sat down for, they give you one question you can't quite answer yet, and they make you feel clever for noticing something.

Get two out of three and you've got a decent opener. Get all three and people are still quoting it in the group chat a decade later.

The Hall of Fame

1. Doctor Who — 'The Eleventh Hour' (2010) A little girl in a garden, a crack in the wall, and a strange man falling out of the sky and asking for an apple. It's a fairytale told in ninety seconds, and it resets an entire series without a single line of exposition. The reason it works is that it treats a child's bedtime fear as completely legitimate. Matthew Smith's Doctor is funny, then quietly serious, and you're eleven years old again whether you like it or not.

2. Killing Eve — series one, episode one (2018) A café in Vienna, a small girl, a man in the corner chair, and the politest act of violence you've ever seen performed with an ice cream. The genius isn't the shock — it's the timing. The scene takes its time, lets you settle, lets you think you know where it's going, and then doesn't. Villanelle is fully formed before the titles roll. Most shows take a whole series to introduce a character that clearly.

3. Gavin & Stacey — series one, episode one (2007) Two houses, two phones, two families shouting over each other about a wedding nobody has agreed to yet. It's the entire premise of the show delivered as a comic relay race, and it quietly establishes the class geography of the whole series without a single character explaining themselves. Very few sitcoms have ever been this efficient.

4. The Office (UK) — series one, episode one (2001) David Brent, to camera, explaining that he's a friend first, boss second, probably entertainer third. Three words in and you know exactly what you're dealing with. The cold open here is doing something sneakier than it looks: it's teaching you the grammar of the mockumentary — the glance, the pause, the little check to see if the camera liked that — before you've had a chance to find it odd.

5. Peep Show — series one, episode one (2003) Mark talking us through his flat, his flatmate and his general disappointment, before we've met anyone else. The POV conceit could so easily have been a gimmick you had to be sold on. Instead it's established casually, almost apologetically, so that by the time the titles arrive you've already accepted that you live in Mark's head.

6. Broadchurch — series one, episode one (2013) A boy, a cliff edge, and a town that has no idea what's about to happen to it. It's a masterclass in restraint: no music sting, no dramatic zoom, just a small figure in a big landscape and a horrible sense of inevitability. ITV drama spent years trying to bottle that opening again.

7. Derry Girls — series one, episode one (2018) Erin's diary voiceover, a family in chaos, and a background of soldiers and checkpoints treated as entirely ordinary. The trick of Derry Girls was always that the extraordinary is furniture. The cold open tells you that before you've had time to brace yourself, and it's why the show could be hilarious and devastating in the same breath.

8. Ghosts — BBC run (2019–2023) Ghosts turned the cold open into a house style. Ninety seconds of bickering in a hallway, a bit of physical comedy, one character being theatrically appalled — done. It's the sitcom equivalent of a warm-up act that's actually better than the headliner, and it trained an audience to expect a gag before the theme tune every single week.

9. Slow Horses — series one (2022) River Cartwright, a training exercise, an airport, and a career ending in real time. It's a proper spy opener: you don't understand the stakes until roughly forty seconds after the scene has finished, and by then the titles are already rolling and you're already committed.

10. The Traitors — the 2026 launch Say what you like about reality telly's habit of over-narrating everything, but the opening of this year's Traitors run did the one thing a cold open must do: it dropped a group of strangers into a room, let the silence do the work, and reminded you why the format is still the best thing on telly in January. No explanation, no recap, no 'previously'. Just nerves.

Where the stragglers go wrong

A slow pan over a city skyline is not a cold open. Nor is a caption reading 'three months earlier'. Nor is a moody cover of a pop song playing over five separate people staring out of windows.

These aren't openings, they're admin. If the first ninety seconds could be swapped with the first ninety seconds of any other drama on any other channel without anyone noticing, you haven't written a cold open. You've written a screensaver.

The other common crime is the pre-credits spoiler: a show that shows you the body, the explosion or the affair before the titles, then spends the episode catching up. Fine if you've got a twist. Exhausting if you do it every week.

Three rules worth nicking

• Start mid-argument. Two people already disagreeing is always more interesting than two people introducing themselves.
• Hold one thing back. Give the audience something they can't place yet — a look, a name, a prop on a table.
• Land on a question, not a punchline. The best cold opens end on a beat that makes you lean forward rather than lean back.

None of this is expensive. It's just writing. Which is why the shows that do it well deserve a small, annual round of applause. From us, at least — before the theme tune, obviously.
