Continuity mistake: In the scene just after Robin Hood jumps from the top of the burning castle, Skippy, the little boy rabbit is hanging on to Little John's arm. He first has three fingers and a thumb, then after a brief shot of the water, he has four fingers and a thumb. He switches back to three fingers and a thumb a few shots later.
Continuity mistake: The Sheriff shoots his final shot and hits the bull's eye straight on. When Robin shoots, the Sheriff knocks the arrow into the air. Robin corrects the arrow's angle with another shot and the arrow also hits the bull's eye, splitting the Sheriff's arrow. But since it approached from an angle, there's no way it could split it right the way down the length of it.
Continuity mistake: After Robin Hood and Little John ran from the sherrif and his posse in the woods and swing up the tree you can see that both of them don't have arrows penetrating their clothing but after the sheriff and his posse leave you can clearly see that Little John had an arrow in his shirt and Robin Hood had an arrow in his hat.
Continuity mistake: During the archery contest fight, Little John starts in his disguise, then changes into his green clothes then back to his disguise.
Continuity mistake: Near the beginning of the film, when the young rabbit fires his arrow over the castle wall, it appears to fall into an enclosed courtyard. But when Maid Marian first notices him, as he picks it up again, there is no wall behind her.
Continuity mistake: The Jewels in Prince John's crown change; a triangle of little red stones appears while he is thrashing around on top of the burning castle shortly before the film ends, in place of the larger red and green ones from earlier on.
Continuity mistake: In the scene with the citizens of Nottingham are in prison there is a rabbit (with the bow and arrow). He has a chain around his leg. When the people are rescued the chain has moved to his neck.
Revealing mistake: Just before the archery contest, the Elephants play their trumpet sounds. Both the times they play it, you can notice that the same scene has been used twice.
Plot hole: After Little John bores a hole in the bottom of the treasure box, several gold coins fall through the hole. The four rhinos holding the box should have noticed it becoming lighter.
