Throughout the movie Belleros has a piece of leather wrapped around his upper right arm. But after fighting with Orthos, the piece of leather switches to his left arm. It then switches back to his right arm for the rest of the movie.
When the Pegasus is wounded by the Chimera, we see the claw marks and blood on its left side. Yet, only a minute later the claw marks and blood have moved to its right side.
When Belleros & Philony are walking through the woods, she is wearing a blue cloak over her right shoulder but just before the scene changes the cloak is suddenly over her left shoulder.
When Philony gives Belleros her father's sword, the closeup shows the hem of her cloak running along her right shoulder but in the long shot the cloak covers the entire shoulder.
When they decide to deal with Orthos followed by the Chimera, Philony moves her bow to her left hand before picking up the quiver but in the next frame the bow is back in her right hand.
After Belleros & Philony rescue Tello they walk past the man who Belleros killed but he is obviously still breathing.
When Belleros' father shoots the dragon at the start of the film, he is stood in the tall grass on the left of the beast with the ocean on the right side but his arrow strikes on the right of the animal.
Pegasus is not afraid to attack the Chimera but when Orthos unties him he just shies away without making any attempt to escape or attack. He is not even tied to the tree, his reins were just hanging from a twig, so he could have walked forward and escaped at any time.
Belleros shows no signs of discomfort in later scenes after being wounded by the arrow yet we didn't see him treat the wound. His tunic shows no sign of a hole or the blood before the fight with Orthos but at no time did we see him change clothes or clean them up.
Actae tells Orthos that Belleros & Philony freed the prisoners & the king asks where. Actae replies "Not far. 20 leagues." A league is roughly 3 miles so not far is a gross understatement.
