Pupils from schools in Watford and St Albans were given a sneak preview of the Warner Bros. Studio Tour London - The Making of Harry Potter last week.

Students from Leavesden Green School JMI and Loreto College visited the studios in Aerodrome Way, Leavesden, where BBC television programme Blue Peter was being broadcasted, for a special live show from the tour’s Great Hall.

As well as meeting presenters Helen and Barney, children were treated to a live performance by boyband JLS at the event on Thursday, March 22.

Warner Bros. Studio Tour London - The Making of Harry Potter will open to the general public on March 31.
