An open casting call is to be held to find a girl to star in J.K Rowling's Harry Potter spin-off film Fantastic Beasts and Where to Find Them.

Film studio Warner Bros is looking for a girl between the ages of eight and 12 to play the character of Modesty.

"Modesty is a haunted young girl with an inner strength and stillness," the studio said. "She has an ability to see deep into people and understand them."

The casting call will take place at the Excel Centre in London on Saturday.

The chosen youngster will star opposite Eddie Redmayne in what is bound to be one of the biggest film releases of next year.

Rowling has written the screenplay for the film, which is based on a Harry Potter spin-off book she published in 2001.
