Which J.K. Rowling novel was adapted into the two-part film finale of the Harry Potter series?

Harry Potter and the Deathly Hallows was adapted into the two-part film finale of the Harry Potter series.

The novel is the seventh and final main Harry Potter book, published in 2007. Warner Bros. divided its film adaptation into Harry Potter and the Deathly Hallows – Part 1 and Part 2, released in 2010 and 2011 respectively. This made the overall film series eight movies from seven novels.

The story follows Harry, Ron, and Hermione as they leave Hogwarts to search for Horcruxes and confront Lord Voldemort. Splitting the adaptation allowed the filmmakers to retain more plot and character material from the longest concluding storyline.

A common mix-up is to identify Half-Blood Prince as the finale because it was the sixth book and the last single novel adapted before the split. Deathly Hallows is the only Rowling Harry Potter novel given two feature-film adaptations.
