Film producers will hold an open casting in east London for a young star to appear in the forthcoming Harry Potter spinoff Fantastic Beasts And Where To Find Them.

While Warner Bros have cast the major roles in JK Rowling’s Potter prequel, including Eddie Redmayne as the main character, they now want to find a girl aged between eight and 12 to play Modesty, a “haunted young girl with an inner strength and stillness”.

A similar process gave Daniel Radcliffe, Emma Watson and Rupert Grint their stellar careers when Harry Potter And The Philosoper’s Stone was adapted.

Auditions take place from 9am on Saturday, July 18, at the Excel Centre in Docklands. Hopefuls should just turn up (get there early).
