Corrected entry: When Wallace picks up the box of porridge with the bite mark in it, the porridge would have fallen out before it really does.
Corrected entry: In Wallace's house you can see all the sheep, and there are about a hundred at least. There are also about this many when they are in the fields. In all the other scenes, including in the truck and when they all stand up on the motorcycle, there are only about 50 or so.
Correction: There aren't that many when Gromit breaks out of prison, nor when they are in the warehouse at the end. The whole point of the sheep in the field is that they weren't all among Wallace's team, or else Preston wouldn't have known they'd be there when he went rustling. Also, we don't know that Preston successfully kidnapped all the sheep from that field, some may have escaped. It seems that Wallace hand picked his 'Sheep Snatch Squad' from among the best of those at his home, and then having broken Gromit out of prison they acquired a few extra members.
Corrected entry: Gromit bends the wooden ladder, and we hear the sound of rubber.
Correction: This is not a normal ladder. It is one which has been designed with a specific purpose in mind. Namely, being rammed into a grate at 50 mph in order to easily facilitate the transit of a window-cleaning dog to the necessary height to begin his work. Of course such a ladder as this would be made out of a material far more flexible and supple than wood. This is a common occurence in a world of flying sidecars piloted by dogs with human intelligence, which can fire huge dollops of porridge at sheep-rustling robots.
Corrected entry: When they are washing Shaun in the "Knit-o-Matic", the light changes from "wash" to "light shave" due to a fault. However, at one point Wallace says "Do something Gromit", and if you look at the console after this the light is back to "wash" again even though it is doing the light shave.
Correction: Time and again in this film and 'A Grand Day Out' and 'The Wrong Trousers' it is demonstrated that Wallace's inventions have a life of their own. Sometimes they work, sometimes they don't, sometimes somewhere in between. This is one of those times.
Corrected entry: After the robot put Preston through the spiky mincing machine thing at the end, we see his innards being put into lots and lots of cans and in just about every can is an eye. Preston only had 2 eyes.
Correction: Only two of the cans have eyballs in them. One has a hand, and one has his spiked collar, but you only see two eyeballs.
Correction: The porridge, as we've seen when the breakfast machine misfires and when Gromit fires from the sidecar-plane upon Preston's truck, is one which is extremely thick when prepared. The contents of the box settled before Wallace picked it up, and the motion he used to take the box off the shelf caused the porridge to spill.
