Nox

An after-hours Hallowe'en event at Warner Bros. Studio Tour London with Death Eaters, trick-or-treat stations and a Forbidden Forest trail; over 12s only.

Nox is an after-hours Hallowe'en event held across three nights at Warner Bros. Studio Tour London, running during the Studio Tour's Dark Arts feature. Visitors enter the Great Hall beneath a ceiling of Jack-o-Lanterns before being sent on a trail through the darkened Studio Tour, stopping at trick-or-treat stations for sweets inspired by the Harry Potter films. Along the way there's a lantern-lit Forbidden Forest trail, Death Eaters storming the Backlot with a duel at the Hogwarts bridge, and a chance to stop by Gringotts Wizarding Bank to collect a bag of chocolate coins before heading down a Death Eater-patrolled Diagon Alley. Tickets cost £150 and include after-hours admission, one misting mocktail or cocktail served in the Great Hall, one piece of confectionery at each trick-or-treat station, and a free souvenir digital photograph, with drink bars available for extra purchases. Event registration opens from 6pm, the Studio Tour experience runs from your entry time until 11:45pm, and the site closes at midnight. This event is open to over 12s only and is now sold out for 2026.
