Ralph Fiennes has expressed his desire to reprise his role as Voldemort in an upcoming HBO TV adaptation of the Harry Potter series. However, he believes the role has already been cast, with HBO boss Casey Bloys stating they don't know who will play the role. The series will also feature Warwick Davis as Professor Filius Flitwick. Some cast members have faced criticism for participating in the series for their roles, particularly from those opposed to JK Rowling's views on trans rights.
