Will the new Harry Potter TV series become HBO’s most-watched show upon release?
The upcoming series based on Harry Potter and the Philosopher's Stone has already generated massive attention, with its trailer becoming the most viewed in the history of HBO and HBO Max — surpassing previous records by more than double. The show introduces a new cast, including Dominic McLaughlin as Harry, while following the original story that made stars of Daniel Radcliffe, Emma Watson, and Rupert Grint. However, the project also faces controversy surrounding J.K. Rowling, which could affect audience reception despite strong initial hype. The key uncertainty is whether record-breaking trailer performance will convert into actual viewership dominance.
