Warner Bros. Studio Tour London - The Making Of Harry Potter

This post was last updated June 2023.

We have visited the Warner Bros Studio Tour in London quite a few times now over the years and every time we have visited we have seen something different whether it's something we missed last time or whether it was a special event such as the addition of the Forbidden Forest or Gringotts Bank. The Warner Bros Studios brings to real life the magical world of Harry Potter and it is a must see for Harry Potter fans.

What To Expect Warner Bros. Studio Tour - The Making Of Harry Potter (Sat Nav WD25 7LR)
First of all I must mention this is not a theme park. The Harry Potter Studio Tour takes you behind the scenes of the Harry Potter films. It is a self guided tour which you can enjoy at your own leisure. It's a magical experience which will transport you in to the Harry Potter world. The experience is broken in to six different sections. Sets, Props, Costumes, Visual and Special Effects, Creature Effects and The Art Department.

Your Tour Has Now Begun!

Costumes from Harry Potter


Great Hall 
Serving as the backdrop to some of the film series’ most iconic scenes such as the Yule Ball and the Battle of Hogwarts, the Great Hall was first built for Harry Potter and the Philosopher's Stone in 2000 and was used as a key set for six more films.

Forbidden Forest 
The Forbidden Forest seen at the Studio Tour is filled with 19 trees each with a diameter of over 12 feet.

Platform 9 and 3/4 at King's Cross Train Station 
Most of the scenes that take place on Platform 9 ¾ were actually shot on location at King’s Cross Station in London, however, during Harry Potter and the Deathly Hallows – Part 2, part of the station platform was recreated on a soundstage at the Leavesden Studios, complete with the track and the train. 

Diagon Alley 
The Diagon Alley set constantly changed throughout the film series. Since its construction, walls have shifted, shop fronts have moved and entire buildings have been carefully tweaked, leaning just slightly, to create the street that is seen in the films.

Gringotts Wizarding Bank 
From Harry Potter first discovering Diagon Alley to the famous trio escaping on a Ukrainian Ironbelly dragon in their quest for a Horcrux, Gringotts Wizarding Bank played an important role in the Harry Potter film series.

Professor Sprouts Greenhouse 
The greenhouse is a fan-favourite set from the Harry Potter film series, where students were taught their Herbology lessons with Professor Pomona Sprout. 

The burrow

Potions Classroom 
Over 950 potion jars line the walls of the classroom, each with unique props kept inside them including baked animal bones from a local butcher shop, dried leaves, herbs and shrunken heads made by the props department. 

Memory Cabinet 
Nearly 900 memory vials and labels were created for the cabinet that can be found in Professor Dumbledore’s office.

Professor Umbridge's Office 
Great attention was paid to the inside of the only pink office in the Ministry of Magic, belonging to Professor Dolores Umbridge, including her collection of plates featuring various moving kittens.

Puking Pastilles 
Stocking everything from Extendable Ears to fireworks, Weasleys’ Wizard Wheezes was designed to look like an 18th century storefront and took more than three months to build 

The chamber of secrets


Filmmakers faced a huge challenge when turning the wizarding sport of Quidditch into a real sport they could capture on film. Quidditch uniforms evolved throughout the film series, going from thick robes in the first two films to lighter, sportier robes with the players name and number on the back in the later films.

19 Years Later 
When tasked with creating outfits for the scene Costume Designer, Jany Temime wanted to keep to a similar palette of pinks, oranges, blues and browns seen throughout the film series. 

Yule Ball 
The Yule Ball held to celebrate Christmas and the Triwizard Tournament presented an opportunity for the Costume Department to create a more formal style of wizard wear.

The “French Blue” fabric of the Beauxbatons uniform was chosen to stand out from the muted blacks, browns and greys of the other school colours.


The Chamber Of Secrets Door 
Often mistaken for a Visual Effect, the Chamber of Secrets door is actually a fully operational door created by the Special Effects team based upon sketches provided by the Art Department.

Invisibility Cloak
Gifted to Harry in Harry Potter and the Philosopher’s Stone, the Invisibility Cloak features prominently in the films. 

Whomping Willow
The temperamental tree began as a sketch from the Art Department which then had to be made into a real Whomping Willow for Harry Potter and the Chamber of Secrets. 

Green Screen 
Filmmakers often shoot visual effects scenes on a green screen, which allows them to replace the green colours with a completely different background or computer-generated set.

The Basilisk that lives deep below Hogwarts in Harry Potter and the Chamber of Secrets was created through a mixture of Practical and Visual effects.

Three life-size animatronic versions of Buckbeak the Hippogriff were created for the Harry Potter film series: one standing, another rearing and a third lying down.

Goblin Heads 
Goblins in the Harry Potter film series act as bank officials and tellers at Gringotts bank in Diagon Alley. 

Created by Nick Dudman, Creature and Make-Up Effects Designer, with help from Production Designer Stuart Craig, Aragog had a leg span of over 18 feet and was even able to crawl out of a hole and deliver dialogue in Harry Potter and the Chamber of Secrets.


Graphic Design 
The Art Department were responsible for designing and creating thousands of props that helped to bring the visual world of Harry Potter to life on screen. 

White Card Models 
During the filming process, before the actual set construction began, the Art Department would create a white card model of the set/location.

Technical Drawings 
Dozens of concept artists, illustrators and art directors created every environment, prop and character of the Harry Potter film series.

Hogwarts Castle 
The jewel in the crown of the art department is the intricately detailed model of Hogwarts castle. Built for the first film, Harry Potter and the Philosopher's Stone, the model's every courtyard, tower and turret were filmed and enhanced with digital effects to create unforgettably realistic views of the magical school.

The Hogwarts Express

The amount of time it take is up to you. It took us about 4 hours to walk around the tour. We are huge fans of the Harry Potter movies so we didn't want to miss anything. As you walk around there are staff on hand to answer any questions you may have and also offering you the chance to earn badges to take home.

There are interactive experiences you can enjoy along the WB Studio tours such as the broomstick challenge. You wait your turn then hover your hand over the broom to make it rise up, just like in the flying lesson in the first movie. 

There is a chance to ride a broomstick or ride in Ron's car in front of a green screen. This is not included in your ticket price. You can purchase a photograph or video to take home.

The Wizarding World is home to untold secrets – so many in fact, even Dumbledore doesn’t claim to know them all. Harry Potter certainly uncovered a few during his adventures at Hogwarts and now it’s your turn to discover hidden magic with Enchanted Keys.

Placed throughout the Studio Tour, Enchanted Keys unlock secrets, quizzes, videos and more to enhance your visit. To unlock them, you’ll need the free Harry Potter Fan Club app – the official Harry Potter and Fantastic Beasts companion.

If you find an Enchanted Key at the Studio Tour:

Download the Harry Potter Fan Club app
Log in, tap the key symbol in the Discover tab
Scan the Enchanted Key to uncover its secrets
The Harry Potter Fan Club app is available to download on the App Store or you can get it on Google Play.

Once you scan an Enchanted Key with the Harry Potter Fan Club app, you’ll be rewarded with an exclusive piece of content related to the area of the Studio Tour you’re in – so keep a Seeker’s eye out for every Enchanted Key to make the most of your visit.

If you get stuck, be sure to ask a member of staff. After all, help will always be given to those who ask for it.

Open times vary depending on the time of year you may visit so it is always best to visit the website for up to date opening times.
