Continuity mistake: When Robin and Azeem are escaping on horseback from the sheriff's men at Marian's castle, crossbows are being fired at them from the left side and one hits Robin's horse. When Robin pulls the crossbow bolt from his horse a minute later he pulls it from the horse's right side. (00:35:05 - 00:36:00)
Continuity mistake: Just before the 'one true weapon' speech, one of the villagers shows Robin what the soldiers did to his son, Will walks toward Robin and pulls his dagger from its scabbard, after Azeem says 'if it's fame you seek.' the camera goes back to Will and he is no longer carrying it. In the behind shots, it can be seen back inside its scabbard. (00:55:00)
Continuity mistake: When the soldiers are taking anything valuable out of a village church, when they put up a wanted poster outside, Robin shoots an arrow into the poster and then Little John rips it of the wall and shows it to the men. When someone says, "Give it back" the soldiers drop what they are holding, and the poster is still on the wall with the arrow through it. (01:00:00)
Continuity mistake: When Robin and his men steal the cart of brew and Friar Tuck, the Friar's trousers (that he is wearing under his brown robe) change colour repeatedly between shots.When he is singing, and when he is trying to sit up after the men have opened the chest of money, the are flesh coloured (cream). But when he has been hit on the head by the branch and falls from the cart, they are brown. (01:05:40 - 01:06:45)
Factual error: Robin and Azeem land at the white cliffs and Robin says something like, 'Tonight we will dine with my father'. Those white cliffs are the Seven Sisters in East Sussex, about 200 miles from Nottingham. It would probably take about two weeks to walk it. They also reach Hadrian's Wall in the next scene, which is 200 miles further north than Nottingham.
Continuity mistake: When Robin heroically swings across to Fanny and the child in the Sherwood Forest battle scene: He swings straight across, with the rope's focal point fixed between himself and Fanny. Then he gives the rope to Fanny to swing across to John. This time the focal point is between her and John. Someone somehow managed to "move" the rope in order to move the plot along. That was jolly nice of them wasn't it?
Factual error: When Azeem goes to pray he starts by kneeling on the ground and soon afterwards he bows down. The Muslim prayer sequence starts by standing up for quite some time then one bow, up again followed by two kneeling bows then up again. Also, Muslims do not put their palms together for prayer as Azeem does, rather their hands are either at their side or crossed.
