A new walking tour taking visitors behind the scenes of the Harry Potter movies has been unveiled by Warner Bros Entertainment at Leavesden Studios in Hertfordshire, UK.

Warner Bros Studio Tour London-The Making of Harry Potter comprises some of the most iconic sets from the film series, including the Great Hall and Hogwarts bridge.

US-based exhibition company Thinkwell are behind the design of the studio tour attraction, which spans more than 150,000sq ft (13,935sq m) at Warner Bros' Leavesden complex.

Warner Bros Studio Tour London vice president Sarah Roots said: "What makes this tour so special is that everything on show has been used in the making of the Harry Potter film series.

"All the sets, props and costumes are authentic and show the incredible detail and craftsmanship that goes into film production. All the films were shot at Leavesden, so it's wonderful to be giving the sets a permanent home here."
