LONDON — The Japanese-born British composer Youki Yamamoto, who arranged the score for “Harry Potter and the Goblet of Fire,” is to be among the main international jury at one of Europe’s top children’s and youth film festivals in Zlin, Czech Republic.

The festival, which opens its 51st edition May 29, has gained a reputation for showcasing top talent and productions.

Yamamoto, who moved to Britain from Yokohama at age 10, graduated from London’s Royal Academy of Music and has been composing for films for the past decade.

He joins Czech director Jan Hrebejk, artist Galina Miklinova and Bulgarian actor Ivan Barnev on the main jury.

In other jury appointments, Czech film writer Jaroslav Sedlacek and Hungarian animator and director Bela Ternovsky — a past winner of the festival’s Golden Slipper for best animated film — are to join the European debut jury.

“International festivals are not only judged by the quality of their competitive films, but also by the quality of their juries,” said the fest artistic director Petr Koliha.
