AIn Greek mythology, the Titans were 12 children of the earth goddess Gaia and the sky god Uranus. Their story appears at the beginning of the movie when it explains that they ruled the earth until they were overthrown by their own children Zeus, Poseidon, and Hades.

AThe remake tells essentially the same story (i.e., Perseus (Sam Worthington), cast as a baby upon the water by his grandfather but rescued and raised by a fisherman, obtains the Pegasus and slays the Medusa (Natalia Vodianova) in order to save the princess Andromeda (Alexa Davalos) from being eaten by the Kraken), but many of the details and special effects have been altered to appeal to a modern audience. In the original, the characters of Andromeda and Calibos have much larger roles. Characters like Poseidon, Ammon, Pegasus, Hera, and Thetis, who played key parts in the original, either do not appear or have much smaller roles in the remake. Characters in the remake, like Draco (Mads Mikkelsen), Hades (Ralph Fiennes), Io (Gemma Arterton), and the harpies, do not appear at all in the original. Andromeda, not Io, is Perseus's love interest in the original. The original also ends with Perseus marrying Andromeda and becoming king, something he rejects in the remake. Some things the two films have in common are the visit to the Stygian witches, the scorpion attack, the battle with Medusa, the final battle with the Kraken, and the fact that Perseus is the son of Zeus (Liam Neeson).
