Leavesden, England — Nox, the after-hours Halloween event at Warner Bros. Studio Tour London, returned for three nights, October 29, 30 and 31, 2026, with tickets at £150. During Nox, guests explored the studio’s authentic Harry Potter sets after dark during the Dark Arts feature, came face to face with Death Eaters, walked a lantern-lit Forbidden Forest, and collected trick-or-treat sweets along the way.
Step into the shadows and delve into the dark arts during this spine-chilling, after-hours event.
Inside the Great Hall and the Dark Arts Feature
The night began in the Great Hall, dressed for Halloween as it appeared on screen.
Explore the authentic Harry Potter sets, props and costumes after hours during the Studio Tour’s Dark Arts feature. Enter the Great Hall under a ceiling of Jack-o-Lantern pumpkins, as seen in Harry Potter and the Philosopher’s Stone. We caution you to be on your guard as Death Eaters could storm Hogwarts at any moment!
The Trail: Forbidden Forest, Diagon Alley, and a Duel at the Hogwarts Bridge
From the Great Hall, guests were sent on a trail through the darkened Studio Tour, stopping at trick-or-treat stations for sweets inspired by the films, through the Forbidden Forest, the Backlot and Diagon Alley.
Dare to enter the Forbidden Forest? You’ll find your path is only lit with lanterns against the fearsome creatures who lurk in the shadows.
Throughout the evening, a heightened number of Death Eaters will be storming the Studio Tour Backlot. Come face-to-face with Lord Voldemort’s supporters in an epic duel at the Hogwarts bridge.
Guests also stopped by Gringotts Wizarding Bank for a bag of chocolate coins before heading down a Diagon Alley patrolled by Voldemort’s followers.

Each Nox ticket covered:
- After-hours admission to the Studio Tour during the Dark Arts feature
- One misting mocktail or cocktail, served in the Great Hall
- One piece of confectionery at each trick-or-treat station
