United Kingdom: Hertfordshire – Harry Potter, Warner Bros. Studio
Wands, Weasleys and Butterbeer: A Night at the Warner Bros. Harry Potter Studios
It was a cold, cloudy Tuesday evening in December when we pulled into the car park at Warner Bros. Studio Tour London in Leavesden, Hertfordshire, and joined what seemed like half the wizarding world queuing outside. Karen had been wanting to do this for years. I had been quietly sceptical. By the time we left, three hours later, I had completely come round to her way of thinking. It really is rather good.
The studio itself sits on the site of the old Leavesden Aerodrome, a former de Havilland aircraft factory that was used during the Second World War and then converted into a film studio in the 1990s. Warner Bros. took it over in 2000 specifically to film the Harry Potter series, and they more or less never left. The eight films were shot here between 2000 and 2010, with the studio covering around 30 acres of Hertfordshire countryside — not exactly glamorous countryside, it has to be said, but it does the job.
The tour itself opened to the public in March 2012, after a reported £100 million investment to convert the working studios into an attraction. It covers two enormous sound stages, an outdoor backlot and several smaller exhibition spaces, and it houses what is claimed to be one of the largest collections of original film props, costumes and sets in the world. On the evening we visited, it was doing a brisk trade.
🎟️ Getting In and the Great Hall
Tickets are timed entry, which is sensible given the numbers, and ours were for 6 pm. After collecting them at the desk and buying the obligatory wristbands, we were herded into a holding area that showed clips from the films and then — with a certain amount of theatrical buildup — into a small cinema for a short introductory film. Harry, Hermione and Ron all appeared on screen to tell us how important this place was. Karen was already delighted.
Then the screen rose, the doors behind it opened, and there it was: the Great Hall of Hogwarts, pretty much exactly as it appears in the films, and dressed out for Christmas in a way that made Karen audibly gasp. The studio runs a Hogwarts in the Snow event each year from mid-November through to early January, and the Great Hall gets the full treatment: twelve enormous Christmas trees, one for each of the film’s principal cast members, decorated in the colours of the four houses and standing in a row down the centre of the room. The long house tables were laid as though for the Christmas feast — turkey, roast potatoes, crackers and all — with fake snow dusted across the surfaces and real frost effects on the windows. It is genuinely impressive. The hall was originally built for Harry Potter and the Philosopher’s Stone in 2000 — the first of the eight films, based on J.K. Rowling’s 1997 debut novel — and was used, with various modifications, throughout the series. The production designer Stuart Craig, who worked on all eight films, designed the Great Hall to be slightly larger than the book described it, to give the camera more room to breathe. At Christmas, with the trees and the candles and the fake snow, it felt enormous and rather beautiful. Good call, Stuart. We were given about ten minutes in the Great Hall before being let loose into the main exhibition, which sprawled across the two enormous sound stages and seemed to go on forever. There was a lot to take in.
🧙 Through the Sound Stages
The main exhibition follows a rough chronological path through the films, though you are free to wander at your own pace, which we did. The first thing that struck us was the sheer volume of stuff. Every prop, every costume, every set dressing looked exactly as it had on screen — because, of course, it was exactly what had been on screen.
Dumbledore’s office was an early highlight. The circular room was packed with the instruments and books and oddities that appeared throughout the films, including the Pensieve, the stone basin used for storing and reviewing memories, which featured prominently from Goblet of Fire (2005) onwards. The office set was first built for Chamber of Secrets (2002) and refined over subsequent films as the character of Albus Dumbledore evolved — first under Richard Harris, who died in October 2002 shortly after the second film was completed, and then under Michael Gambon, who took over from Prisoner of Azkaban (2004) onwards.
Nearby was the Gryffindor common room, which felt remarkably cosy for a draughty Scottish castle, and the boys’ dormitory with its four-poster beds. Karen sat on one of the beds for a photograph. I did not argue.
The Potions classroom — all black wood and strange jars — was followed by the Defence Against the Dark Arts classroom, and then by a corridor of creature costumes that stopped us in our tracks. The Goblin costumes from the Gringotts Bank scenes were extraordinary: each one took eight hours to apply on filming days, and the goblins were played by actors as short as 4 feet 5 inches, most of whom trained extensively to walk and move in a specific, slightly hunched way. There was a time when I would have called that an overly specialised career choice. I no longer say things like that.
The section on special effects was particularly interesting for two people who had spent years watching the films without a clue how any of it was done. Flying sequences were filmed against enormous green screens, with actors suspended on wire rigs that could be removed digitally in post-production. The broomsticks were mounted on pneumatic rigs that could pitch and roll at high speed, which sounds rather unpleasant for the people sitting on them, and apparently was. Daniel Radcliffe, Emma Watson and Rupert Grint spent a considerable amount of their teenage years strapped to things.
🍺 Butterbeer Break in the Backlot
Roughly halfway round, the tour opens out onto the backlot, and this is where we stopped for Butterbeer. There is a proper outdoor canteen area out here, and for the Hogwarts in the Snow event the whole backlot gets a dusting of fake snow — the cobbles, the rooftops, the Knight Bus, all of it. On a genuinely cold and cloudy December evening, with real breath misting in the air and artificial snow settling on our shoulders, it felt rather appropriate. Neither of us was going to miss the Butterbeer opportunity regardless. Butterbeer is a fictional drink from the books and films — described by Rowling as tasting a little bit like less-sickly butterscotch — and the studio’s version comes cold or hot, in a souvenir cup if you want one, which of course we did.
The hot version was basically a warm, sweet cream soda with a thick butterscotch foam on top. It was extremely sweet. Karen loved it. I got about three-quarters of the way through mine before my teeth started to object. Neither of us regretted ordering it.
While we drank, we had a look around the backlot itself, which contains the Knight Bus, the Dursleys’ house from Privet Drive and the covered bridge from Hogwarts. The Knight Bus — the triple-decker purple bus that appears in Prisoner of Azkaban — was built from a modified Bristol Lodekka double-decker, extended upwards with a third deck. The Dursleys’ house facade, complete with the number 4 on the door, was built as a street set in the studio grounds rather than filmed at a real house, though early exterior shots in Philosopher’s Stone used a real street in Bracknell, Berkshire, before the productions shifted entirely to the studio in later films.
✨ Diagon Alley and the Final Stretch
Back inside for the second half, and the undoubted highlight of the whole tour: a full recreation of Diagon Alley, the magical shopping street that appears throughout the films. Stuart Craig and his team built Diagon Alley as a working set, with every shopfront dressed and stocked — Ollivanders Wand Shop, Gringotts Bank, Madam Malkin’s Robes for All Occasions, Weasleys’ Wizard Wheezes with its vivid orange exterior. Walking down it in the evening light, with the cobbles underfoot and the crooked buildings rising on either side — and with garlands and wreaths hung across the shopfronts for Christmas — felt oddly real. Karen said it felt like being inside the book. She is not wrong.
The exhibition then moved through the artwork and design process — thousands of concept drawings and storyboards showing how each location and creature was developed from Rowling’s descriptions into something that could be built and filmed. The amount of work that went into things the camera barely lingers on was genuinely staggering. There were detailed drawings for every brick in Diagon Alley, every label on every bottle in Snape’s classroom.
The model room came next: a vast, detailed architectural model of Hogwarts Castle that was used as a reference throughout all eight films. It is about 50 feet across, built at a 1:24 scale, and took a team of artists around 74 weeks to construct. When we were there, it was lit to simulate dusk, which made it look exactly as it does in the films. Several children nearby were completely speechless, which is not a condition I usually associate with children in tourist attractions.
