These fresh faces join a talented lineup including John Lithgow as Dumbledore, Nick Frost as Hagrid, Janet McTeer as Minerva McGonagall, and Paapa Essiedu as Severus Snape—who were previously announced. The three young actors portraying Harry, Ron, and Hermione were revealed back in May. Filming is set to take place at Warner Bros Studios Leavesden in Hertfordshire, the same location where the eight original films were produced.

HBO has articulated a commitment to delivering a faithful adaptation of the series, allowing for a more in-depth exploration of the intricacies found in the books due to the TV format's flexibility. Notable production staff has also been confirmed, including director of photography Adriano Goldman and hair and makeup designer Cate Hall, both of whom boast experience from the acclaimed series The Crown. The first season of the Harry Potter TV series is slated for release in 2027.
