It was announced today that the Knight Bus – as seen in Harry Potter and the Prisoner of Azkaban – would be a part of Warner Bros. Studio Tour London: The Making of Harry Potter.

The triple-decker bus is an actual vehicle, explains special effects supervisor John Richardson!

John Richardson, Special Effects Supervisor, said: “The Knight Bus was not a CGI Creation as many people thought but in fact a real-life working bus. It was constructed by cutting up two iconic Routemaster buses, reworking the structure and bolting it all back together to provide one bus with three decks. One interesting challenge that arose during the shooting of Harry Potter and the Prisoner of Azkaban was that we could not drive the vehicle across London due to the number of low bridges in and around the capital. This meant that we had to transport the bus in two pieces between locations and put it back together as required for filming.”

The Studio Tour will be opening March 31st, and more information can be learned here. Photos of the bus on set can be seen below:
