Thousands of teenage girls waited patiently in long lines to audition Saturday for a role in the next Harry Potter film.

The girls, aged 13 to 16, were trying out for the part of trainee wizard Luna Lovegood in "Harry Potter And The Order Of The Phoenix."

In the book, Luna is described as being an unusual character who is considered somewhat of an outsider by her classmates. With her wand tucked behind her ear for safekeeping and a necklace of corks, the 14-year-old wizard often appears somewhat detached from what is going on around her.

The successful auditioner will join cast members Daniel Radcliffe, who plays Harry; Emma Watson, who is Hermione Granger; and Rupert Grint, who plays Ron Weasley.

First in line outside Westminster Central Hall in London was Kim Allen, 15, who said she had been waiting in line since 11 p.m. Friday.

"I desperately want the part. I check the Harry Potter Web site every day and saw the auditions advertised on there."

Only British and Irish citizens were being auditioned, and each hopeful had to identify herself with a passport or birth certificate, and a proof of address.
