History Trivia / PercyJacksonAndTheOlympians

** He ''did'' say, however, that he found the movie's take on Smelly Gabe's ultimate fate to be ActuallyPrettyFunny.

* DisownedAdaptation: Rick Riordan dislikes the movie adaptations of his books, and has gone on record about it numerous times.

* DawsonCasting: The titular character's sidekicks fall under this even after bumping their age up from the novels. In the book, Annabeth is 13, while in the movie she's 16, and actress Alexandria Daddario was 24 at the time of filming. Similarly, Brandon T. Jackson was 25 also playing a high schooler. This is even more jarring considering that in their most prominent roles coming into the film, they were already playing adults -- Daddario in ''Series/WhiteCollar'' and Jackson in ''Film/TropicThunder''. This sequel was filmed three years later, with Logan Lerman now in his early 20s as well. Justified in Grover's case, who ''is'' 24 during the events of ''The Lightning Thief'' and looks his age, too (although he's pretty much the satyr equivalent of a 12-year-old).

* DisownedAdaptation: Rick Riordan does not like the movie adaptations of his books, and has gone on record about it numerous times.

** The St. Louis Arch sequence was in the original script draft of the film, but the Chimera was considered "too weird-looking" and unrelatable for the audience to connect to and was thus replaced by the Hydra.

* DoingItForTheArt: Uma Thurman actually worked with a snake wrangler to hold and interact with several live snakes. This helped her understand how Medusa would feel with snakes growing out of her head.

* AuthorsSavingThrow: Riordan admitted in a 2007 blog post that the reason he provided the explanation of Athena has "brain children" was solely to satisfy readers who wanted to know how Athena could have kids, if, according to the original mythology, she is a virgin goddess. He also confesses that the real reason why he made Athena able to have kids was solely because [[RuleOfCool a demigod child of Athena was too cool to not include.]]

* DawsonCasting: The titular character's sidekicks fall under this even after bumping their age up from the novels. In the book, Annabeth is 13, while in the movie she's 16, and actress Alexandria Daddario was 24 at the time of filming. Similarly, Brandon T. Jackson was 25 also playing a high schooler. This is even more jarring considering that in their most prominent roles coming into the film, they were already playing adults -- Daddario in ''Series/WhiteCollar'' and Jackson in ''Film/TropicThunder''. This sequel was filmed three years later, with Logan Lerman now in his early 20s as well. Justified in Grover's case, as he is said to look older than the others (he has a goatee in the first book already) and is in fact 24, although since satyrs age half as fast as humans, he is the equivalent of a human 12-year-old.

* DyeingForYourArt: Alexandria Daddario colours her hair blonde for the second movie, as does Kristin Stokes for the musical. James Hayden Rodriguez (Luke in the Lortel run, the national tour, and the cast album) briefly did this as well, before returning to his former shaved look.
