The Story

HBO’s Harry Potter series is leaning into the book. The new teaser for Harry Potter and the Philosopher’s Stone, released September 1, adds scenes that the books only mention or never show (HarryPotter.com).

It opens with Hermione walking the Hogwarts Express before she meets Harry and Ron, asking Lavender Brown and Hannah Abbott, “Did you love the summer reading?” There’s also a look inside the Burrow, where Ron’s first Hogwarts letter gets splattered with Fred and George’s ketchup (HarryPotter.com).

There are book-accurate moments too: Harry failing to turn a match into a needle in Transfiguration, the Sorting Hat speaking through the rip in its brim, Fluffy and the troll. Snape gets his say: “Let’s hope you show some talent on the Quidditch pitch, Potter” (HarryPotter.com).

The series debuts at Christmas 2026 on HBO and streams exclusively on HBO Max. Francesca Gardiner writes and executive produces, and Mark Mylod directs multiple episodes (HarryPotter.com).
