Is it a bird? Is it a plane? No, it’s Aunt Marge!

London’s Tower Bridge got an unusual addition to its skyline, as Aunt Marge from “Harry Potter” was seen levitating above the Thames, baffling tourists and locals alike with her unexpected aerial performance.

Tipping the scales at 95 kgs and spanning an impressive 11.7m in circumference, this massive Aunt Marge hovered as if by magic, a whopping 6.5 meters off the ground, inflated with 40m3 of air—enough to keep a party going for days.

The launch celebrated the new “Return to Azkaban” exhibit at the Warner Bros. Studio Tour London – The Making of Harry Potter, which marks the 20th anniversary of the film’s release.

A team of 16 specialists, including designers, artists, and seamstresses, dedicated a total of 264 hours to craft this spectacle. The project involved 46 hours of initial design and sketching, 18 hours of detailed painting of her face and hair, and 32 hours of tailoring her less-than-flattering outfit.

Laura Sinclair-Lazell, Head of Show Experience at Warner Bros. Studio Tour London, remarked, “It’s a surprise for many that this iconic scene wasn’t a CGI creation but was brought to life through the exceptional talents of our film crew.”

During the original filming of the scene, a concerted effort from the cast, camera and lighting crews, stunt coordinators, and the special effects team was essential for creating the memorable spectacle of Aunt Marge’s unintentional take-off.

The special exhibit will run from May 1st to September 4th and is included in the Studio Tour ticket price, which must be booked in advance.

Laura Sinclair-Lazell added, “We’re excited to offer visitors a deeper look into the behind-the-scenes magic of the third Harry Potter film.”
