Dark Arts

Halloween-themed event at Warner Bros. Studio Tour London with floating pumpkins, Death Eaters and Dementors.

Warner Bros. Studio Tour London dims the lights for its Dark Arts feature, running from 16th September to 8th November 2026 (with 2027 dates confirmed for 24th September to 7th November). Visitors can see the Great Hall decorated with over 100 floating pumpkins above a sweet feast as seen in Harry Potter and the Philosopher's Stone, try duelling techniques in a Defence Against the Dark Arts classroom, and keep watch for Dementors in the Forbidden Forest, where a demonstration uses lighting and water-based smoke effects. Death Eater performance actors appear throughout the Studio Tour in costume, with lighting, sound effects and pyrotechnics specifically at Hagrid's hut, the Hogwarts Express and Diagon Alley, plus lighting and sound effects at the Hogwarts Bridge from 6pm. New for 2026, there's a Secrets of Sound Effects feature with a Halloween twist, and the Creatures Workshop reveals how a combination of practical models and CGI brought Nagini to life on screen. Dark Arts-themed food and drink is available at the Dragon Roasted Café, Food Hall, Frog Café and Backlot Café, and there's the option to book The Hogwarts Table for dinner or afternoon tea with Dark Arts specials. All extra features are included in the standard ticket price, and tickets must be booked in advance. Anyone wanting to avoid the Death Eater or Dementor elements can ask a team member to be routed around them.
