What is the title of the sixth film in the Harry Potter series?

The sixth film in the Harry Potter series is Harry Potter and the Half-Blood Prince.

Released in 2009, the film adapts the sixth novel and follows Harry’s increasingly direct conflict with Voldemort. Albus Dumbledore gives Harry private lessons about Voldemort’s past, while Hogwarts becomes more dangerous as the wizarding war intensifies.

The title refers to the mysterious owner of an annotated Potions textbook. Harry uses the book’s instructions to excel in class, but its identity and history become important to the wider plot.

The film sits between Order of the Phoenix and the two-part Deathly Hallows adaptation. It is often confused with the seventh story because both deal heavily with Voldemort’s past and the destruction of his Horcruxes, but Half-Blood Prince is the sixth film.
