Thus far, HBO has yet to confirm any of the cast members who are slated to appear in Harry Potter. Ralph Fiennes, who played the evil wizard Lord Voldemort in the films, has endorsed Cillian Murphy as his successor. Other actors rumored to be up for roles on the show include Brett Goldstein as Rubeus Hagrid and Paapa Essiedu as Severus Snape.

Professor Albus Dumbledore was portrayed by Richard Harris in the first two Harry Potter films. After Harris’ passing in 2002, Michael Gambon took over the role for the remaining six movies. Jude Law later played a younger version of the character in the Fantastic Beasts film series.
