Which Harry Potter novel was split into two films in the J.K. Rowling film series?

Harry Potter and the Deathly Hallows was split into two films in the J.K. Rowling film series.

The adaptation was released as Harry Potter and the Deathly Hallows – Part 1 in 2010 and Harry Potter and the Deathly Hallows – Part 2 in 2011. Together, the two movies adapt Rowling’s seventh and final Harry Potter novel.

The split allowed the filmmakers to retain more of the book’s plot, including the trio’s search for Horcruxes, the significance of the Deathly Hallows, and the final Battle of Hogwarts. Part 1 follows Harry, Ron, and Hermione after they leave school to continue their mission against Voldemort.

The earlier six novels each received one main feature-film adaptation. This is why the seven-book series became an eight-film series, a fact sometimes incorrectly described as the result of an additional spin-off movie.
