Harry Potter fans are being given the chance to star in the sixth Potter film, with two key parts up for grabs.
Evanna Lynch beat 15,000 hopefuls to land the part of Luna Lovegood
Warner Brothers is holding open casting sessions in London to fill the roles of Lavender Brown and Tom Riddle.
A similar process gave 14-year-old Evanna Lynch her first film role, as Luna Lovegood, in the forthcoming Harry Potter and the Order of the Phoenix.
Both roles require actors between the ages of 15 and 18. Auditions will be held in London's Earls Court in July.
The sixth Potter film, Harry Potter and the Half Blood Prince, is the penultimate chapter in the series.
Based on JK Rowling's book, it sees Lavender Brown, a pupil in Harry Potter's year at Hogwarts School for Witchcraft and Wizardry, dating Potter's best friend, Ron Weasley.
Warner Brothers Pictures says it is looking for a "pretty and lively girl" who "tends to be either laughing or crying hysterically".
Tom Riddle is a darker character who is "very charismatic".
Film producers say that "staff and children are probably all a little scared of him".
The audition for Lavender Brown will be held on Sunday 1 July, and for Tom Riddle on Sunday 8 July.
Both will take place at the Earl's Court Exhibition Centre, West London. Applications will be received from 1000 BST (0900GMT) and the queue will close at 1300BST (1200GMT).
