CBBC Newsround will be interviewing Bonnie Wright (Ginny Weasley), Matthew Lewis (Neville Longbottom), Evanna Lynch (Luna Lovegood) and Katie Leung (Cho Chang) with questions submitted to them by fans. If you’d like to submit a question (or two), you’d best hurry – the deadline is Friday morning (May 4).

The answers from the best questions will come out in June.
