The first season of the "Harry Potter" series will be released only on December 25, 2026, but HBO is already preparing to start filming the sequel, which will adapt "The Chamber of Secrets," any day now. Releasing new seasons annually will not be possible due to the scale of production. Nevertheless, HBO head Casey Bloys assured Deadline in an interview that the breaks between them would not reach two years:
"No. We are trying our best to release the sequel as quickly as possible. The break between seasons will not be two years, but we are trying to shorten it as much as possible."
Earlier, it was reported that the creators want to find a balance between production speed and the workload on the actors and film crew. They have to speed up, in part, due to the age of the young performers, who will grow up with their characters.
Initially, HBO presented the new "Harry Potter" adaptation as a ten-year project. However, given the breaks between seasons, adapting all seven books may ultimately extend beyond this timeframe.
