1.Let's start off with the fact that Hades delivers this line at the 46-minute mark, the halfway point of the 92-minute movie.
2.When Herc enters Phil's hut, he bangs his head on the mast of the Argo. In Greek mythology, a fallen mast is exactly what killed Jason, the captain of the Argo, when it hit him on the head.
3.Pain and Panic shapeshift into snakes to kill baby Hercules because in the myths, Hera sent down two snakes to do the same thing. They failed in the myth and movie, with Herc beating them both up.
4.Hercules meets Meg by saving her from the river monster, Nessos. This is exactly how he meets one of his wives, Deianira, in the myths.
5.In the scene where two kids are trapped under a boulder, one shouts, "Somebody call IX-I-I," which is 9-1-1 in Roman numerals.
6.In "I Won't Say I'm In Love," the muses take on the same shape of the busts in Disney's Haunted Mansion ride.
7.When Hercules imprints his hands in cement among famous gods and heroes, it's marked "To Sid." This is a reference to Sid Grauman, the founder of the Chinese Theater, where the handprints of many famous celebs are in the forecourt.
8.When Phil says, "Two words: I am retired," it would translate to "Είμαι συνταξιούχος" in Greek, which is two words.
9.The statue that Hercules breaks when he skips a rock is the Venus de Milo, a 100 BC Grecian sculpture found on the island of Melos missing its arms. It's currently housed at the Louvre.
10.Speaking of art, the walls of Hercules's mortal childhood home are decorated with the Spring Akrotiri fresco, a real fresco found on modern-day Santorini and painted in the Bronze Age.
11.When Hermes delivers flowers to Zeus and Hera, he looks like the logo for FTD Flowers, which uses an illustration of Mercury, Hermes's name in Roman mythology.
12.When the fates tell Hades that the planets will align in 18 years, only six planets are shown. Only five planets were known (excluding Earth) in ancient times, as they were the only ones that could be seen with the naked eye.
13.Some of the 12 labors from the original myth are included in the film like fighting the Erymanthian boar, the Stymphalian birds, and the Nemean lion during the song "Zero to Hero."
14.As Meg and Herc are falling in love, she accidentally gets poked in the back by Cupid's arrow.
15.While the muses sang about Hercules's rise to fame, they mention crowds going wild and him selling merchandise. This wasn't too far from how famous athletes in ancient Greece were treated. They would get fans, fame, and sculptures made of them.
16.Lastly, during the final battle, Hercules takes a page out of Homer's Greek epic, The Odyssey, to defeat the Cyclops. In The Odyssey, the main character Odysseus heats the end of a timber and stabs the Cyclops in the eye. This is exactly what Hercules does in the movie.
