I apologize for my previous response. I made a mistake in my initial answer. There are indeed fewer Harry Potter books than movies.
To answer your question more thoroughly, I'll provide some reasons why the film franchise has more entries than the book series.
Expanded Storytelling: While the Harry Potter books are beloved by fans for their rich world-building and character development, there are certain limitations to literature.
Splitting the Final Book: As mentioned in the previous response, the decision to split the final book in the series, "Harry Potter and the Deathly Hallows," into two movies was likely a factor in why there are more Harry Potter movies than books.
Spin-Offs and Prequels: In recent years, the Harry Potter franchise has expanded beyond the original series with spin-off films like "Fantastic Beasts and Where to Find Them" and its sequels.
