Isaacs – who famously portrayed Lucius Malfoy in the Harry Potter franchise – will play Peter Groff, Mr Groff’s “more successful and not very modest oldest brother” who Mr Groff is living with following his split from his wife, Maureen. Kirke – previously in HBO’s Girls – will star as the new headmistress Hope, a former Moordale student with grand plans to restore the school’s reputation. Recording artist and songwriter Saleh will make her acting debut as Cal, a nonbinary student at Moordale who “instantly clashes with Hope’s new vision for the school”.
