Continuity: During the first night in the castle, Shrek walks to the door of their room and his ears wilt. In the following pan shot to the king's balcony, his ears are standing up again. There is no time in which he could have voluntarily changed them.

Continuity: When Sherk is reading Fiona's diary his fingers change position every time the camera changes.

Continuity: Puss saves the Gingerbread Man from drowning in the castle's moat by catching him with his sword, however, he is on Donkey's back and the drawbridge is a couple of meters above the water. So the sword would have to have been 2-3 meters long to get down to the Gingerbread Man.

Continuity: Just one shot before Pinnochio is finally tangled in stripes, we can see his limbs are only a little bit wrapped in stripes, and then we see him tangled completely in stripes many times.

Other: In the scene where Shrek wakes up to find himself human in the barn, Puss is holding the potion bottle, reading its disclaimer. What is wrong, is the shadows on the floor (casting behind him) don't match the shadows on his body (casting to the right side).

Continuity: When the request is made by the messenger to have Shrek and Fiona come to Far Far Away for the wedding party, as the trumpeteers troop off in the background you can see their footprints on the ground. However, when the same view is shown again seconds later the footprints are gone.

Continuity: In the beginning scene at the tower, just after Prince Charming slides down the rope across the lake of lava, you can see a small flock of birds flying around the highest point of the tower. In the shot after Charming uses his breath spray, the birds are nowhere to be seen.

Continuity: When the fairy tale creatures are watching T.V., the Gingerbread Man drops a buffalo wing to the floor in astonishment, but a couple shots later it's gone.

Continuity: When the pig is holding onto the fairy godmother's leg, his hat falls off and lands underneath. But as the fight for the wand continues, that hat disappears.

Audio problem: Shortly after Fiona's dog is introduced, he is seen on the sofa while Shrek and Fiona are talking. The dog yips throughout the scene, but early on he yips twice and only opens his mouth once. Dogs must move their jaws when they bark, otherwise it sounds like a whine instead.
