HBO Max’s Harry Potter television series is reportedly scheduled to begin filming its second season in August 2026, before the first season has premiered. The rapid turnaround reflects HBO’s plan to adapt roughly one Hogwarts school year per season while keeping pace with its young cast as they grow older.

Season 1 is due to debut on HBO Max on Christmas Day, 25 December 2026, meaning production on the next instalment could start months earlier. The series is intended to give J.K. Rowling’s books more screen time than the films, potentially including storylines and classroom material that received less attention in the original adaptations.
