Other mistake: During the Battle of Teth (the pillared jungle planet), the AT-TE's shoot the ledge at the top and there's not a single mark on the ledge afterwards, despite being hit with several joules worth of fire.
Other mistake: On the ship, Wall-E leaves dirtmarks everywhere, except when he's hiding behind an EVA pod. (00:37:20)
Other mistake: When Horton first crosses the bridge he breaks all of the planks. Then at the end when the angry mob goes to get him, they seem to have crossed the fully broken bridge to get to the other side.
Other mistake: Judging the angle Teetsi leaps towards Alex at, there is no way that he would hit him in the eye.
Other mistake: When Schadenfreude is playing the piano the first time he's on screen, he starts off by playing a slow, dark piece. Right before the piece turns to a more jazzy, upbeat number, he plays three final chords: The first is higher then the others, the second is lower, and the third is somewhere in the middle. But, if you watch his hands, the first two chords were mixed up: the first chord is played with his left hand on the lower half of the piano, and the second is played with his right hand, visibly on the higher keys. This doesn't match the audio, as the chord was supposed to be lower then the first, not higher.
Other mistake: After the flood, Ponyo uses her magic to enlarge the ship along with all its accessories. At the end of the journey, Ponyo loses her magical powers and the ship shrinks back along with all the ship's accessories. A captain's hat is among the shrunk accessories, although Sosuke used it from the beginning of the film and it was always adult human size.
Other mistake: When the villagers return to their homes, Po is seen emerging from an alley obscured with dust. In the shot where we can only see his profile, Po's "cape" is blowing in the wind, but the dust does not seem to be affected.
Suggested correction: You'd have been correct if the only inconsistency was a misaligned cloak. But that scene is far too elaborate. At first, we see a stereotypical legendary warrior in a long cape and straw hat pacing through magical dust. But soon, Po's figure transforms completely; even the dust vanishes without leaving a trace. I think what we see is either what the villagers thought to have seen or a mirage that the magic dust had cast.
Other mistake: When Fry and Colleen are lying in bed, his hand is around her shoulder but it is the same colour of Colleen's skin. (00:04:25)
Other mistake: When Leela is pumping dark matter, you see the lumps in the hose that's supposed to be the matter. But the nozzle is a regular nozzle, and the balls squeeze through easily, even though they're super-dense, and therefore solid.
