Continuity: When Ditchwater Sal blows the door off her caravan, just after Una stops Yvaine crossing the wall, you see the broken pieces of door fall to the ground. It the next shot they are gone.

Continuity: When Septimus attacks the redheaded farm boy, the position of his knife changes between shots, from the farm boy's throat to behind his ear, several times. Submitted by wizard_of_gore

Revealing: At the end fight scene when Michelle Pfeiffer's character is laughing, you can see that her teeth are only darkened in the front, not the rear.

Deliberate "mistake": The pony pulling Ditchwater Sal's cart changes throughout the movie. This would be so as to not overwork any one animal. It is most noticeable in the scene when Una is driving the cart after Yvaine. When she is in the city, the pony has a white stripe all the way down its face; when it is galloping in the forest, it has two separate white spots on its face; and the pony that Tristan detaches from the cart and rides has one spot on its face. Also when Tristan detaches the pony, it only has on riding gear (a saddle and bridle), whereas earlier in the scene it only has on a harness for pulling the cart.

Continuity: When Michelle Pfeiffer is in the coach communicating with her sisters in the mirror, her image goes from old to young back to old again between shots. Submitted by wizard_of_gore

Other: When Septimus finds Primus dead in the bath, the Inn has vanished and the bath is in an open field. As the bath was part of the Inn magically generated from Lamia's small chariot, it should have disappeared along with the Inn. Primus should have been found lying on the ground.
