How Will the Harry Potter TV Series Timeline Work?
The Harry Potter TV series is structured as a long-term project, with each of the seven seasons corresponding to one book in the series. This approach allows for a more expansive and detailed retelling of Harry’s journey from his first year at Hogwarts to the final battle against Voldemort.
