History Literature / PercyJacksonAndTheOlympians

* AscendedExtra: Hestia, who does next to nothing in Greek mythology.

* AdaptationalVillainy: Unlike the books, which averted EverybodyHatesHades, he is a villain in the movie, although not the main villain, Luke.

In the books the Greek gods have moved to the United States, and their home, Olympus, is now located above the Empire State Building. They have many [[HalfHumanHybrid demigod]] children with mortal humans. These demigods [[WeirdnessMagnet attract mythological monsters]], so they have go to a safe haven in Long Island, NY, called Camp Half-Blood, and learn to fight. The books get progressively DarkerAndEdgier throughout the series as a war with the Titans approaches.

* GettingCrapPastTheRadar: Seriously, of all the ways for Mr. D to get Percy's name wrong, his favorite is ''Peter Johnson''? Especially given [[IfYouKnowWhatIMean the reputation of his followers]], back in the day...

** Ganymede is mentioned in one book. His ''[[IfYouKnowWhatIMean special realtionship]]'' with Zeus isn't.

* TooDumbToLive: Nearly everyone at times, but a particularly egregious example is [[spoiler: when they enter Hephaestus' junkyard and after explicitly being told not to touch or take anything, everyone does exactly that. Bianca's death was likely only because she drew the short straw offscreen.]]

* {{God}}: Mentioned in ''The Lightning Thief'' during a handwave by Charon.
--> '''Charon''': ''God'' capital "G" God is something else entirely. We won't delve into the metaphysical.

* {{[[God]]}}: Mentioned in ''The Lightning Thief'' during a handwave by Charon.

* God: Mentioned in ''The Lightning Thief'' during a handwave by Charon.

* [=~Hey, It's That Guy!~=]: The movie seems to be full of this, starring the likes of [[KillBill The Bride]] and [[TheLordOfTheRings Boromir]]/[[GoldenEye 006]] and JamesBond. Not to mention rather than going to Percy, it seems Poseidon could have just had [[{{Rome}} Titus Pullo]] handle things like normal.

** [[spoiler:Actually played with as no one realized their were ''two'' demigod heroes of the prophecy: one was Luke who had to die for things to be set right and the other ''was'' Percy who's choice to [[ICannotSelfTerminate give Luke the knife]] saved Olympus rather then destroy it.]]

* {{God}}: Weirdly hand-waved, or something. In the first book, Percy asks if God is real, and Dionysus talks about that dealing with the metaphysical or something to that effect. After that, the question's never brought up again.
** He said that topic would be "getting metaphysical" and the Olympians don't know if the Abrahamic God exists any more than humans do. So the answer is more of a shrug than a hand-wave.
** The ancient Greeks did in fact have a temple devoted to the "Agnostos Theos" (which means "Unknown God") to keep from angering any gods they might not know about. In the Bible, St. Paul identifies this god as the Christian God.
*** As part of a theological point about the absurdity of the idea and demonstrating that something was missing

* [[{{ptitlebb330lv9nf12}} The Queen's Latin]] / AliensOfLondon: The gods all have British accents in the movie.

* {{Unperson}}: When Zoë Nightshade betrayed her sisters the Hesperides by helping Hades, they kicked her out and any mentions of her were blotted out from recorded myths.

** ''TheHeroesOfOlympus'' takes this a step further, suggesting that the gods ''do'' go around in their Roman aspects and their is an opposite camp for their children.
