Continuity: In the beginning scene, the ruler of Argos is condemning his daughter and son to the sea with a group of guards present at the shore. While he is giving his speech, there is a brief moment when the whole group can be seen getting drenched by a wave crashing ashore, but in the very next moment of his speech - even up to the daughter's cast off - no one is wet.

Continuity: When Perseus is taming Pegasus, a claymation model is used for the long shots of the famous flying horse. However, when it shows Perseus jumping on the back of the real horse, you can clearly see that the horse has no wings. They couldn't figure out a way to strap on fake wings for the close-up?

Other: During the scene when Argos is being destroyed, a citizen falls backward due to the rushing waves and you can see a pair of black running shorts with white trim under his tunic.

Revealing: When Calibos is speaking to Thetis' statue, as he screams "I demand justice", you can see the left horn on his head wiggling around, revealing a flimsy prop.

Continuity: When they are fighting the giant scorpions, there are three distinct scorpions fighting. Each of the remaining men faces a scorpion 1 on 1. One of the men dies fighting, and thats the last we see of that scorpion. Thello kills his scorpion, then throws Perseus his sword who then kills his scorpion. The third one just magically disappears.

Continuity: When it shows the man being burned at the stake in the city, the man is just a wooden carving. As brief as the shots of it are, it's extremely obvious, particularly if you use slow motion. (The use of slow motion is permitted when it reveals things such this.)

Other: When Perseus wakes up in the stadium and he is talking to the old man, you can see a flesh coloured pair of shorts under his tunic.

Continuity: When Calibos gives Andromeda the necklace, he drapes it around her neck (unable to clasp it with his long fake nails). In the next and following shots, the necklace is clasped.

Audio problem: When Perseus starts to swing his rope at Pegasus, the rope is absurdly loud, and is obviously just the same recorded "whoosh" sound repeated four or five times.

Continuity: After getting Pegasus back, Perseus hands the horse's rope lead to Ammon. In the following claymation shot, the rope has disappeared.

Revealing: When the ruler of Argos is cursing his daughter prior to setting her adrift, we are treated to a couple of close ups where his modern dental fillings are beautifully displayed.
