History Film / HarryPotterAndTheHalfBloodPrince

** In the book, Harry and Dumbledore walk into Hogsmeade, passing the three broomsticks as they go. There are book-only plot ramifications for this, but that plot was dropped from the film.

-->'''Harry''': [[LampshadeHanging But, Sir, I thought we weren't allowed to apparate on Hogwarts' grounds]].\\

* ScrewTheRulesIMakeThem: Dumbledore apparates with Harry from the top of the astronomy tower.

But while those events linger over the plot, the action stays fully grounded at Hogwarts. Harry learns more about Voldemort's BackStory, becomes increasingly suspicious of Snape's loyalty and discovers an old potions textbook annotated with powerful spells and useful notes from its previous owner who identifies himself only as "[[TitleDrop The Half-Blood Prince]]". Draco Malfoy is tasked with something by Voldemort himself; [[ArsonMurderAndJaywalking and wacky romantic hijinks ensue for everyone]].

* VomitDiscretionShot: In the sixth movie, Cormac is shown leaning down out of camera shot and vomiting on Snape's shoes.

* * IntoxicationEnsues
** Harry, after imbibing some Felix Felicis in the sixth movie. HilarityEnsues.

* BigShutUp: Harry tries to call a Quidditch tryout to order. He isn't quite loud enough, so Ginny intervenes with a very helpful '''[[HotFuzz "SHUT IT!"]]'''

* CaptainObvious: In ''Half-Blood Prince'':

* CuteGiant: Hagrid's brother, depending on whether he's acting more cute or weird at a moment.
* DramaticCurtainToss: In ''Prince'', every time Draco goes to the wardrobe. It gets silly after a while.
* EveryoneCanSeeIt: Ron and Hermione in ''Half-Blood Prince'', even more so than in the book. Ginny lampshades it in the infirmary scene when leaving Ron and Hermione alone and says, "About time, don't you think?", which also doubles as a huge hint from herself to Harry.
* {{Foreshadowing}}
** In ''Half-Blood Prince'', Harry has a brief reaction to the ring [[spoiler:foreshadowing the fact that Harry himself is a Horcrux]]. This, and other subtle hints towards the events of ''Deathly Hallows'', are due to the fact that this was the first script written where the writers knew how the series ended.

* PromotionToOpeningTitles: Of a sort. ''Half-Blood Prince'' marks the first time Creator/BonnieWright is listed in the main credits instead of just on the list of cast members.

* AscendedExtra: Ginny, who goes from minor character to a rather vital person in Harry's life. [[Film/HarryPotter The film]] at least tries to temper this by giving her a prominent role.

* ForTheEvulz: Presumably the only reason the Death Eaters torch the Burrows in ''Half-Blood Prince'' and the Quidditch pitch in the assault on Hogwarts.
* GilliganCut: Played for laughs in the sixth film, when Harry and Hermione are discussing their date choices to Slughorn's Christmas party:

* HideYourPregnancy: HelenaBonhamCarter (Bellatrix Lestrange) was pregnant during the filming of ''Film/HarryPotterAndTheHalfBloodPrince'', but it would have thrown a major wrench into the plot for Bellatrix to appear pregnant. So she spends that film wearing a loose costume and hiding behind the furniture, especially in the Unbreakable Vow scene.
* KarmaHoudini: Harry, just in the movie. In the book, Harry gets detention for the rest of the year for [[spoiler: casting sectumsempra on Draco]]. In the film, there is not punishment, despite Harry getting in trouble for comparatively minor things in previous movies.
* LastMinuteHookup: [[Film/HarryPotter The film]] rectifies this a bit by expanding Ginny's screen time and giving her more scenes alone with Harry, but in the end it seems like this still.

* RuleOfFunny: For much of the sixth film, theaters were cracking up -- [[DownerEnding at least until the final scenes]].

Followed the final story, which was split into two films ''[[Film/HarryPotterAndTheDeathlyHallows Harry Potter and the Deathly Hallows, parts 1 and 2]]''.

** In ''Half-Blood Prince'', Harry has a brief reaction to the ring [[spoiler:foreshadowing the fact that Harry himself is a Horcrux]]. This, and other subtle hints towards the events of ''Deathly Hallows'', are due to the fact that this was the first script drafted in conjunction with the following film's script.

->'''Albus Dumbledore''': ''This is beyond anything I have imagined''.
