Londoners were left in awe as a colossal dragon, reminiscent of the ones seen in the Harry Potter films, was paraded through the city streets. The 25-foot-long animatronic beast, encased in a massive crate, journeyed past iconic landmarks such as Westminster Bridge and King’s Cross Station en route to Warner Bros. Studio Tour – The Making of Harry Potter in London.

This grand display marked the introduction of ‘Triwizard Tournament – Making of Champions’, a new feature at the Warner Bros. Studio Tour London – The Making of Harry Potter, which is commemorating the 20th anniversary of Harry Potter and The Goblet of Fire.

The gigantic Hungarian Horntail, weighing a hefty 1.3 tonnes, recreated the captivating scene from the film where Harry battles the creature during the initial round of the ‘Triwizard Tournament’.

Crafted by Harry Potter filmmaker and animatronics expert Joe Scott, this lifelike monster features an animated head, mouth, eyes, and even produces terrifying sound effects.

An impressive 750 hours were spent constructing the mythical creature, with a 3D-printed head, 25kg of fibreglass, and 119 hand-applied spikes. Its mouth is filled with 38 resin-printed teeth, replicating the film’s fearsome appearance in meticulous detail.

Guided by the original sketches, computer-generated blueprints, and scans of the actual model from the film, Scott said: “Revisiting the creation of the Hungarian Horntail 20 years on from Harry Potter and the Goblet of Fire has been magical.

“Creating the dragons for the Triwizard Tournament was no mean feat, with engineers, animatronics, designers and the special effects teams all working together to bring them to life. It’s fantastic to see the craftsmanship that went into this on display at the new feature – inspiring visitors with the magic of our filmmaking secrets.”
