Corrected entry: When Costner escapes after slashing Rickman's face, Rickman starts beating up the guard at the gate who let him get away. The shot is at right angles to Rickman throwing the last punch so we can see that his fist misses the guard's face by miles.
Corrected entry: At the end when King Richard makes a surprise appearance at the wedding, Marian calls him by his first name, and remains standing while everyone else bows. It's unlikely that she would show so little decorum, considering he's the king. Being a semi-distant relative would not give her the right to be so casual with him, especially in public, and at a time when sometimes kings' immediate families addressed them as "Your Majesty."
Corrected entry: At the beginning when the prisoners have escaped into the city, they come out through a manhole cover, now I doubt that Jerusalem would have had manholes that far back.
Corrected entry: When the survivors of the Sherwood battle decide to go to Nottingham, Friar Tuck calls them all "daft buggers." It is very clear that his mouth is not moving.
Corrected entry: When Robin has just stolen the Sheriffs horse he picks up a bag of food, which he hits a soldier with. When he rides out of the gates (in the same scene) he throws the bag behind him. However, in the next scene, back at the 'hide-out' he has the bag of food with him.
Corrected entry: When Robin shoots Will through the hand the arrow clearly misses by a mile and passes off screen, Will already has the arrow in his hand and you can see both at the same time.
Corrected entry: This is only relevant to the extended version DVD. At the start of the bonus scene where the Sheriff finds the hole, the scribe writes on a blackboard "How is your bride?". The "s" looks like it does today (i.e. snake shape). Until the early 19th century, the "s" was written to look more like an "f."
Corrected entry: When the Celts storm the forest hideaway, Costner kneels down and fires at the horsemen. He fires the first arrow into a man's chest. The second arrow goes into the same man (posing as a different one) from a different angle and he falls off.
Corrected entry: In the extended version where the Sheriff finds out Mortianna the Witch is his mother, something doesn't make sense. Mortianna says she killed a baby from the castle and replaced it with her own (the infant Sheriff). What would that achieve? As far as anyone in the castle is concerned it would be the same baby and there'd be a new mad old crone hanging around saying it was her charge. She'd be burnt as a witch. Alternatively, they'd realise it was a different baby and Mortianna would still be burnt as a witch and a murderess. Either way, it doesn't make sense that Mortianna would have managed to have stay with the Sheriff whilst he grew up.
Corrected entry: 98% of characters mentioned or featured in this film are entirely fictional, so saying that they didn't exist isn't really a mistake. However the Sheriff of Nottingham is called 'George' at one point. The Sheriff in 1194 and up to the 1200's was Eustace of Edwinstowe. I'm not making that up, even the flimsiest historical research will uncover that fact. The film-makers obviously thought it too much trouble.
Corrected entry: Before the hanging at the end, a boy drops Will's sword. Will walks without picking up his sword. Still, the Sheriff's soldiers find him with the sword on him.
Corrected entry: At the beginning, Peter shouts at the dead Arab: "That's for five years of Hell." The year is 1194, so he has been locked up since the beginning of the Third Crusade which was between the years 1189-1192. He cannot have been locked up from 1189 because King Richard I arrived in the Holy Land only in 1191.
Corrected entry: The small poacher climbs the tree on Hadrian's wall to escape the men chasing him. If you notice we don't see him climb up the trunk of the tree. That's because it's impossible, there is nowhere to put your feet or hands.
Corrected entry: During Robin's fight with the men at Hadrian's Wall, there is a shot when he fires a crossbow and then immediately tosses it away. In the very next shot of Robin, he suddenly has the crossbow again.
Corrected entry: In the scene near the end when the villagers raise the gates into the next courtyard, the aerial shot shows a villager picking up a sword from a dead soldier's body. How did the soldier die in the middle of an empty courtyard?
Corrected entry: There's a scene where they are drinking Madeira wine. The island of Madeira wasn't found until the early 15th century, and wine started to be produced long after...
