 A New Era for the Wizarding World

Unlike the original films, which condensed the books into two-hour experiences, HBO promises a more in-depth exploration of each book’s plot and characters across full seasons. Fans can expect new story layers, more screen time for side characters, and updated visuals supported by today’s special effects.

As filming gets underway, excitement continues to grow for this new take on the magic that defined a generation. HBO's Harry Potter series may well usher in a new era of fandom, while honoring the legacy of the originals.
