THE organisers of this year's Royal International Air Tattoo are expecting a flood of Harry Potter fans at the event as one of the film's stars is making an appearance.

And the star will be available to sign books on the same day that the latest in the saga from JK Rowling, Harry Potter and the Half Blood Prince, is released.

Hogwarts' very own Neville Longbottom, played by Matthew Lewis, who is a plane enthusiast in real life, will be at the air show on Saturday, July 16.

He will be there alongside the Red Arrows pilots who will also be signing autographs.

Matthew will be at the show having finished the filming of the latest blockbuster, Harry Potter and the Goblet of Fire.Visitors to the tattoo will also be able to see planes from across the world and take part in a robot challenge, as well as try to break a world record at the special Guinness World Record

display.
