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.

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.

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.

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.
