Members of the casting department are currently visiting schools across the UK to try and cast the role of the strange fourth year Ravenclaw student. Luna becomes friends with Harry in the fifth adventure despite her rather odd view on life in the wizarding world. She's one of several new characters such as Professor Umbridge.
Aspiring Luna's can also send their details to this address.
