Corrected entry: Shrek and Donkey could not have made jokes about Lord Farquaad's height since they never saw him anywhere before except on a balcony. Shrek has never heard of him before, so cannot have known. (The producers acknowledge this oversight in the DVD commentary.)
Corrected entry: The mice, particularly for BLIND mice, get up the table much too quickly. You see their shadow from the floor and then a second later they're all on top of the tables having a conversation.
Corrected entry: The door on Shrek's outhouse seems to have a problem. In the very beginning of the movie when Shrek comes out of the outhouse, the door stays wide open, like it's just a normal hinged door. But later when he comes out while talking to donkey, the door quickly snaps shut like it has one of those door closing mechanisms on it.
Corrected entry: When Shrek and Donkey are approaching Duloc, in its parking lot, a man in a Lord Farquad costume sees Shrek and is scared by him. The man runs through the waiting line barriers one at a time, but if you watch closely and count the number of times he turns a corner, he runs through many more turns than there are. Even if you don't count, you can see this from the overhead shots.
Corrected entry: After the dragon has flown through the window in the wedding scene, Donkey is on the dragon's head. When the dragon smashes the last window just after the kiss, Donkey has disappeared, but he is back on the dragon's head when he says "I was hoping this would be a happy ending!" (01:17:08)
Corrected entry: When Shrek and Donkey arrive at Dulloc and are about to see Farquaad for the first time, Shrek says something about Donkey being in the right way for a smacked bottom, that is a tribute to Austin Powers who is also played by Mike Myers. If any of you have seen the music video "Beautiful Stranger" by Madonna, Austin Powers says nearly at the end of it that Madonna is going the right way for a smacked bottom.
Corrected entry: Shrek tells Fiona how short Lord Farquaad is, even though in the film he only saw him when he was high up on the balcony. Although his height may seem like something well known throughout the land, Shrek never even knew about Farquaad before going to his castle. He even refers to him as "this Farquaad guy."
Corrected entry: When the dragon shows its mouth (like when it roars), it has no lipstick. When she falls in love with donkey, her lipstick is suddenly there.
Corrected entry: It's just impossible for chandelier to slip onto dragoness' neck - her side triple "horns" (or whatever they are) would just stop it.
