After watching all the Shrek movies 20 million times I've noticed some mistakes. Here is a list.
Shrek (2001)
- During the campfire scene, with the shot that has Shrek looking at the camera, his left eye goes through the left eyelids.
- The Three Blind Mice are turned into horses to pull the coach after the wedding reception, yet they are seen moments later dancing on the organ keys.
- There is a tap on the barrel next to the one that Shrek whacks with the beer mug at the tournament, as seen in the overhead shot. Seconds later, when Donkey uses the same barrel to crush the knights, the tap has disappeared.
- Lord Farquaad summons the Mirror to show him a princess he can marry (to become King of Duloc). The Mirror presents him with Cinderella, who is not a princess in her own right, so Lord Farquaad could not become King by marrying her. Of the choices named by the Mirror, only Snow White and Fiona are princesses.
- When Fiona finishes off the rest of Robin Hood's Merry Men, she cries out a few seconds later that an arrow is stuck in Shrek's butt. However, if one looks in the few shots beforehand, there is none there.
- When Shrek first paints the "Beware Ogre" sign at the beginning, the top left corner is missing from the piece of wood. In the next shot, the top right corner is missing (as if the painting was done on the other side of the wood).
Shrek 2 (2004)
- Puss In Boots rips Shrek's shirt open when fighting in the woods. His shirt stays ripped open for the next few scenes. But as the party arrives at the Fairy Godmother's Factory, Shrek's shirt is no longer ripped open. There is also no seam or other sign of mending.
- The door to Shrek's swamp opens inwards in some scenes and outwards in others and is stopped by the frame each time. It should only be able to open one way.
- When Puss In Boots plants his sword in the ground then jumps out of his boots, his sword, boots and hat are nowhere near any trees or grass. Yet after attacking Puss In Boots lands in his boots, and his boots, sword and hat have moved to being right beside a tree.
- When Fairy Godmother is throwing the books behind her, the book "Snow White" lands on the other books. "Snow White" noticeably changes position between two shots.
Shrek 3 (2007)
- When Snow White rips off her sleeves she has a tattoo on her right shoulder. Later, when she calls the animals to attack the guards, the tattoo is gone.
Shrek 4 (2010)
- Shrek puts the poster on the mirror. Between shots it moves closer to the frame.
- The King and Queen dissapear and their crowns fall to the floor. However the crowns appear on Rumplestiltsken's table.
So that's my list of mistakes, comment below if there are any that I've missed.
