Continuity: When he sees Meg in the river of death, he reaches down and touches it. Then, when he jumps in, he makes a dive of at least 50 feet.

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.

Deliberate "mistake": In Thebes, Phil beats up the guy and he gets a black eye, but seconds later the black eye is gone.

Continuity: In the shot of the gods after Hades makes his joke about moussaka, Dionyssus is close to Aphrodite and Athena's owl is on her left hand. Then as Hades asks "Is this an audience or a mosaic?", Aphrodite is further from Dionyssus, and Athena's owl is on her right hand.

Continuity: 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.

Continuity: In Thebes, when a vendor opens his cloak and asks if he wants on sundial, his fingers go from being underneath the cloak to over it.

Continuity: When Hades says "Here I am kind of river guardian-less" you can see a chess piece of a centaur on the board near to a lot of other pieces. The when Meg flicks the centaur off the board, the other pieces are gone.

Continuity: The amount of vines on the case Phil pulls out of the bushes changes between shots.

Continuity: As the Fates cut their first victim's string of life, between shots they move further away from the nearby window.

Continuity: When the pillars are about to crash on the pot-maker, he has eight pots and his hand. Then after they don't, and he breathes in relief, there are only six pots in his hands.

Continuity: When Hercules is proving to Phil how strong he is, he runs up a dirt hill and throws a part of a statue into the water. After he does this, the hill is now covered in grass.

Continuity: When Hercules arrives in the market with his wheelbarrow, the angle of the brown line on one of the wheels changes between shots.

Continuity: After Hercules slices off the hydra's head a lot of green goop comes out of its neck and forms a large puddle. A few seconds later, as the hydra suddenly sprouts three more heads, the puddle of goop is much smaller.
