Warner Bros. are holding an open casting call for the character of Luna Lovegood in Harry Potter and the Order of the Phoenix on Saturday, according to CBBC Newsround.
Girls must be aged 13-16 and have a valid passport. The casting call will be at Hall Westminster, Storey's Gate, in London:
Applicants should bring a passport to prove their age, and dress warmly - there could be a long wait!
Anybody who doesn't have a passport won't be seen, and neither will girls who don't live in the UK or Ireland, and Luna is the only part they're looking for.
Warner Bros. will be taking photos and calling back girls they're interested in for a proper audition.

[Luna]'s very otherworldly, she's not like anybody else. She's almost an outsider who likes to watch people and she's slightly detached from the world. And she's a very interesting and unusual girl so it's that sort of quality we're looking for.
We have met lots of fantastic girls... but holding an open call is just a way of us making sure there isn't anyone we might have missed. No final decisions have been made.
UPDATE #2: WB sent us the official notice, which adds:
No experience necessary
COME AS YOURSELF – STRICTLY NO MAKE-UP, NO COSTUMES, NO HIGH HEELS.
