All the news on HBO's streaming 'Harry Potter' TV series, including cast, release date, how to watch, development and whether J.K. Rowling will be involved.

Original Harry Potter director Chris Columbus has called the incoming HBO reboot series a "spectacular idea" as it has the potential to better recreate the books. Speaking to People, Columbus said he was restricted by the relatively short runtimes of films when directing Harry Potter and the Sorcerer's Stone and Harry Potter and the Chamber of Secrets.

One of the baddest villains in cinema will need a new actor to play him, and one Harry Potter director knows who it should be.
