In early 2025, get ready for mayhem and hijinks at Warner Bros. Studio Tour London – The Making of Harry Potter as ‘Magical Mischief’ sweeps through the film sets once again.

In the Harry Potter films, a lot of clever filmmaking trickery is going on behind-the-scenes to achieve some of those magical special effects. And next year, visitors to Warner Bros. Studio Tour London can discover some of those wily ruses for themselves with its return of Magical Mischief.

Here's what to expect.

WBSTL-Great-Hall-Magical-Mischief-2025

Reminisce about the Weasley twins’ great escape

Who could forget the triumphant scene where Fred and George Weasley cause unbridled chaos in the Great Hall in the wake of Professor Umbridge’s tyrannic reign over Hogwarts?

When entering the Studio Tour’s Great Hall, look up to discover Fred and George suspended from the ceiling, paying homage to this iconic moment. You’ll also see the swinging pendulum from the exam sequence before the chaos begins.

Whizz through more of the twins’ tomfoolery by enjoying some of their Weasley’s Wizard Wheezes products out on display in Diagon Alley - or check out their matching costumes from when they started the business.

Discover the secrets of the Dursley's floating cake and other magical objects

Oh, the mayhem Dobby causes with his levitating cake! But how did the filmmakers achieve such a difficult special effect in the first place? Fans will be able to find out upon their visit - while gathering up other filmmaking secrets along the way.

Aspiring wizards can even try their hand at making an origami Howler, just like the one delivered to Ron by Mrs Weasley in Harry Potter and the Chamber of Secrets.

Pay homage to the Marauders

The Marauders claimed to be the original mischief-makers of Hogwarts, so this Magical Mischief display wouldn’t be complete without a nod to the best in the business. To celebrate this artful quartet, the costumes of Remus Lupin, Peter Pettigrew, Sirius Black and James Potter will be on display.

Look for Cornish Pixies

Use your activity passport to look out for Cornish Pixies – not the scariest of the magical creatures, but certainly a magical nuisance. They will be dotted around the Studio Tour for you to find!

Magical Mischief begins 25th January to 28th April, 2025 with tickets now available. You can learn more about this feature, alongside everything else, at the Studio Tour’s website.
