Harry Potter and the Half-Blood Prince is a 2009 fantasy film directed by David Yates, the sixth installment in the Harry Potter series. The film follows Harry's sixth year at Hogwarts as the wizarding world grows increasingly dangerous under Lord Voldemort's rising power. Dumbledore enlists Harry's help to retrieve a crucial memory from the new Potions professor, Horace Slughorn, played by Jim Broadbent, that reveals the secret to Voldemort's apparent immortality — the existence of Horcruxes, objects containing fragments of his soul.

Meanwhile, Draco Malfoy carries out a mysterious mission for Voldemort, and Harry discovers an old Potions textbook filled with handwritten spells and notes belonging to the enigmatic "Half-Blood Prince." David Yates crafted the most visually distinctive film in the franchise, employing desaturated, almost monochromatic color grading that gave the production an oppressively dark atmosphere befitting the story's themes of encroaching evil. The film balanced its darker elements with the franchise's most extensive exploration of teenage romance, as Harry, Ron, and Hermione navigate complicated feelings amid the growing threat. Jim Broadbent's performance as the genial but evasive Slughorn was praised as one of the finest additions to the series' already stellar ensemble cast.

The film's devastating climax, which included the death of one of the series' most important characters, represented a point of no return for the franchise. Tom Felton delivered his strongest performance as Draco Malfoy, bringing genuine anguish to a character previously portrayed as a one-dimensional antagonist. Half-Blood Prince earned $934 million worldwide and was considered by many critics to be the most cinematically accomplished film in the series.
