Factual error: When Young Hercules makes the pillars fall in a Domino effect, they go both ways. However, if this were to happen, they would stop the domino effect when they reach the entrance to the market, which doesn't have pillars. The pillars are not in a circle, so there's no way they can both stop at the top of the ring, where the pot seller is. The only way for this to work is if Hercules started the Domino effect at the entrance of the market, with pillars directly across from each other, which he doesn't.
Suggested correction: He throws the pillar he holds towards the opposite side causing it to fall as well.
They do a pulled back shot that shows it falling from the top of the ring.
Factual error: Hercules skips a rock towards a statue in the fountain. There's no way that after doing that the statue would lose both its arms, let alone with no other damage done to it.
Factual error: When Hercules and Phil are flying over Thebes, the ocean is visible nearby. Thebes is nowhere near the ocean.
