Revealing: Robin's sword bends when he presses it against Guy of Gisborne's throat.

Continuity: Right before Wolf climbs down from the tree, the only clouds in the sky are way off in the distance. Wolf climbs down, and the very next shot of the sky is full of clouds.

Continuity: When Robin is testing the river before they cross, the rope that trips him is seen below the water looking bright yellow. But once out of the water, it looks brown with moss on it. (Time)

Continuity: Just after Will is tied to the barrel to be executed and the drums start rolling, there's a wide shot of the whole gallows, including the barrel, but Will is missing.

Audio problem: When Wolf attacks Will before the hangings, the guards pull him off and he says "Kill him." But his mouth doesn't move.

Continuity: When John is standing on the platform looking across at his trapped wife, there's a piece of the railing next to him that's sometimes on fire, sometimes not.

Revealing: When the sheriff's men are robbing a church, they post a "wanted" sign for Robin Hood. From the front the sign looks fine, but from the side it looks very shiny, like it's laminated.

Continuity: When Robin is talking to the Bishop in his private chambers, they're sitting by the window. They're both lit on the side of their faces that are near the window, but for some reason in the Bishop's closeups, he has harsh white light on the other side of his face as well. Not only is there no source for this light, but in the wide shot that side of his face isn't lit.

Continuity: When Robin and John are fighting in the river, John has his stick under Robin's, and forces it around in a 360 degree motion twice - once in the wide shot, and immediately again in the closeup.

Factual error: Think of the '100 billion dollars' scene in Austin Powers 2, where the President laughs because that kind of money doesn't even exist. You now have an idea how ridiculous it is that a twelfth century outlaw stealing tax money and robbing travellers could get anything like '4 million' as the scribe mentions. King Richard's ransom was only something like 100,000.

Continuity: In addition to the other mistake of Robin crashing through the window that's obviously made of paper - when he first comes through, he makes a hole in the middle, but some of the window is still intact around the outside of the window frame. When it cuts back to Robin a second later, however, there is no "glass" in the frame at all.

Continuity: Either some of the scenes take place over several years, or the leaves of Sherwood switch instantly between autumn-brown and spring-green.

Continuity: As Robin begins to distract Mary from aiming the arrow you will notice that at the wide angle shot she picks up a brown fletched arrow. As the shot tightens it is a white fletched arrow.

Continuity: When Will tells the sheriff he'll have to "respectfully decline" his execution, from one angle his hands are behind him holding onto the gallows, but from another angle they're outstretched.

Audio problem: When Robin and his men have Friar Tuck pulling the wagon you can hear the men singing, but in the shot facing them, their lips are not moving.

Factual error: What's that 'arrow-cam' shot all about? Later on in the film Robin shoots at the hanging ropes and the arrow spins. This is correct for arrows travelling in a straight line. Its physically impossible for an arrow to weave and wobble in the way that the 'arrow-cam' shows and travel in a perfectly straight line.

Continuity: This one takes place in the main battle scene in the forest.  Robin holds a rope, swings around, knocks a man off his horse, and lands on the thatched roof.  The next shot shows him shooting an arrow, but this time (and this time only) he's holding the bow left-handed, not right-handed.

Revealing: The fallen tree from which Robin gives his inspirational speech about freedom has obviously had several branches removed with a chainsaw. It may be hard to see the marks of the blade on a copy of the video, but in the cinema they were pretty obvious.

Continuity: Wolf (the boy) has semi-long, shaggy hair that hangs over his ears and eyes. During the archery contest, however, when Robin has to distract him by flicking his ear with the end of an arrow, his hair has been carefully slicked back to expose his ear.

Deliberate "mistake": In the scene with the forest battle, the scene with flaming arrows being fired was filmed on grass (look at the ground) in a separate location, because it wasn't safe to fire them in a real forest. (Time)
