Continuity: When the members of the League are attacked at Dorian's home, the fight is accompanied throughout by a blizzard of paper falling from a height, yet hardly any of the books have been disturbed on their shelves.

Revealing: Mr Hyde makes no bubbles when growling underwater.

Factual error: In a shot near the beginning of the film, the gravestone for Allan Quatermain's son is misspelled "Quartermain". [People are trying to correct this, saying the spelling's correct - no it's not: http://uk.imdb.com/Title?0311429.]

Continuity: The invisible man is seen in one shot with cream covering the majority of the front of his face but it ends towards the middle of his head. When he is in the automobile, the cream is now completely covering his head and neck. Then, when they go to see Dorian Gray, only his face is covered with make-up again.

Revealing: In the mountain scene where the League is staking out the fortress from a very cold cave, there is no breath to be seen.

Visible crew/equipment: When the Nautilus starts exploding after the record is played, there is a shot of things being thrown about in the chamber, and you can see the cables used to pull all the furniture to the left.

Visible crew/equipment: When Hyde is first brought aboard the Nautilus, he is loosely chained, but still tossing crewmen about. There is one crewman, whose back is toward the audience, whose striped shirt puckers around the harness as he is jerked backwards.

Continuity: When the Nautilus leaves London, before it goes under water, the actors are all standing on deck. In the shot where Mrs Harker is talking to Dorian there are chairs on deck (which is quite remarkable for a submarine). When everybody goes inside because the submarine is about to dive, the chairs are gone.

Revealing: When Skinner is walking around in the snow, after he says he's standing outside completely naked, he should have been leaving footprints in the snow. When he does, between shots, they're practically floating.

Continuity: When the building explodes in the beginning, the man sent to recruit Quatermain walks close to him. When it cuts the man is a few feet away from Quatermain.

Visible crew/equipment: In the shot where Quatermain shoots at three of the attackers they are attached to wires you see running across the floor, probably needed to trigger off the sparks from their steel armor.

Continuity: When Gray stabs Mina and pulls the sword out of her body the blade is clean, only in close-up when he wipes it there are blood stains.

Revealing: In the scene where Allan Quatermain is waiting for Skinner in the snow and the white tiger shows up, when the camera shows a close-up of Allan, there is snow inside his goggles on his head. If it is snowing hard and the snow inside his goggles isn't adding up, it should have been melting or been melted. But it doesn't change at all, which proves it to be fake snow. How did it get in there anyway?

Factual error: In Venice, Quatermain hunts down M in a cemetery, only there is no cemetery in Venice. The burial ground is on the island of San Michele in the lagoon.

Revealing: In the scene early on in the movie where Quatermain fights the goons in the bar, it is quite easy to notice when it is Sean Connery, and when it is his stunt double.

Factual error: In the first few scenes they show some newspapers. They show something like Tuesday April 10, 1899, then Thursday May 18th,1899. If April 10th is on a Tuesday, then May 18th can't be on a Thursday, it would be on a Friday.

Continuity: When Quatermain realizes that Skinner is in his room (on the Nautilus), he puts out the lamp and the room goes black. We hear a scuffle and then the door opens and lights the room and we see Quatermain throwing the invisible Skinner out the door. But when Quatermain shuts the door, the room does not go dark again.

Other: Before Quatermain shoots the fourth attacker long distance he puts on his glasses, cursing his getting old. However, when he aims he looks over the rim.

Plot hole: When the team plays back the record, it contains an extremely high-pitched tone which triggers the crystal sensors on the ship. But the speech on the record is low quality. This low quality would be the result of extreme frequencies being lost; but if they were, the trigger tone (a VERY extreme frequency) would be lost too. If the League's gramophones are capable of recording and playing such a tone, they should also be able to record and play back the speech without any quality loss.

Plot hole: What on earth are those sailors doing with Hyde when he is chained up on The Nautilus? He is solidly chained to the floor and walls and they keep stepping up to him to allow him to swat them out of the way, risking injury or even death. They stand around like idiots as if waiting their turn to walk up to Hyde and be belted across the room. Why? Why are they even there? Hyde doesn't need subduing, and if he needed guarding they could do it without getting into range.
