It’s been 13 lucky years since the last Harry Potter movie was released.
And now, in honour of September 1 being back to Hogwarts Day, we have more details on the upcoming Harry Potter HBO series.
Keep reading to find out everything we know about HBO’s new Harry Potter series including cast, filming, what the show will be about and which stars are set to return.
What is the release date?
The series is expected to release on HBO and HBO Max in 2027.
HBO has planned the series to run over 10 years, with each season focusing on a singular book.
Similar to the movies, but with time for much more detail to be explored.
What is the new Harry Potter series about?
HBO’s new series is about the same thing as the books: Harry Potter’s life at Hogwarts and his fight against Voldemort. So, similar to the films we’ll be able to watch the cast grow up as the series progresses.
The series will unpack each book in a single season. Based on the number of novels, this means we can assume there will be around seven seasons.
This means that we’re likely to get back beloved moments we lost to the books—like Deathday Parties!—and unpack plotlines and details the movie run time was forced to skim over.
HBO refers to the production as a “faithful adaptation,” so we feel confident our treasured storylines and characters will be served well.
