Factual error: How did they get the Nautilus up the Thames? Or into Venice? They'd have had to dredge the river to get it into London. Also, what's really under Venice? I thought Venice was built on a marsh, why would there be all those nifty tunnels and columns under there, why not just foundations and such?
Other mistake: When Sawyer fires at the men on the roof in Venice, he shoots over 30 bullets from two six-shot revolvers.
Other mistake: When Quatermain impales the henchman at the beginning of the film, the rhino is hung high on the wall and the tip is much higher than the spot the man hits, Quatermain would have to have lifted the man higher than he does to achieve this.
Continuity mistake: When the men attack Quatermain in Africa, at one point he hits one guy with a bottle. The bottle completely shatters and there's nothing left to hold. When it cuts back to Quartermain, he's holding a big piece of a broken bottle.
Suggested correction: You can see the bottle in his hand in the scene where it shatters.
No, you can't. The bottle completely shatters. Then in the next cut he's holding the bottle.
Continuity mistake: In the scene on deck of the Nautilus where Quatermain and Sawyer practice shooting the target balls are lying in a row next to the railing, first five, then four, but before the last shot, four again, although another target has been catapulted into the water. (00:42:20)
Continuity mistake: When Reed and Quatermain arrive in London to meet M and the carriage stops the road is empty. However, when the camera angle changes another carriage is passing by. (00:13:00)
Continuity mistake: How can the invisible man cover his face with white cream so we can see him, but his stubble is visible throughout the movie as dark brown only when he has the cream on his face? It can't be because cream's on it, because then it would be white. (00:19:55)
Suggested correction: This is likely a lighting issue as the actor is famously red haired.
Deliberate mistake: When the police officer is being ran over the tank you see him falling backwards. When it cuts we see his hat being ran over by the tank. However the way the officer was falling there is no way his hat could have landed under the tank's belt as it does in the next shot. (00:01:55)
Revealing mistake: The Germans in the movie, good ones as well as evil ones, speak German with more or less strange accents. (00:03:20 - 00:04:10)
Plot hole: When the Nautilus is in Mongolia, we are shown that there is deep snow everywhere. If this part of the movie takes place in July or August, why would there be any snow at all? Even the Yukon doesn't have snow in the summer, except for the northernmost portion of the province. (01:15:20)
Suggested correction: Mongolia is known for wildly changing weather patterns. Sudden snow or hail is common there, they are at an elevated position and is also set more than a hundred years ago.
Continuity mistake: In the scene where Quatermain first meets M, they're in a library with a long table in the middle. When Quatermain sits down in the chair, a folder magically appears which wasn't there before in the other shots. (00:14:15 - 00:15:15)
Continuity mistake: From the meeting with M to Dorian Grey's place, the amount of makeup showing Skinner's head varies too quickly to be real.
Factual error: In Kenya, Alan Quatermain pushes a guy back with a table and impales him on a horn on the wall. The table hides the wound, but the horn punches through. If this guy was impaled on that horn, it would have some blood on it. However, it's just as totally clean as it was before.
Continuity mistake: When The Phantom kicks Quatermain's gun along the floor we see the gun landing close to the wall. In fact the tip of the gun even sticks a bit in to a hole in the wall. When Quatermain a few seconds later picks the gun up the gun has moved at least a feet away from the wall. (00:24:40)
Continuity mistake: At the very end of the movie, Tom Sawyer works the lever action on his Winchester rifle before laying it on Quatermain's grave. On this type of firearm working the lever-action cocks the hammer, but a moment later we see a close up of the grave and the hammer is down. (01:41:40 - 01:42:30)
Revealing mistake: Just before the Britannia Club blows up, Sanderson Reed steps through the poisoned guy's wrist.
Other mistake: In the scene when the League are attacking the factory, we see Captain Nemo demonstrating his skill with his sabre. In the last shot before the scene changes, he cuts down a number of people and then sheathes his sword all in one movement. The camera angle is from the side where his scabbard is hung, and although you can hear the hissing sound of the blade being sheathed you can see the sword completely misses the scabbard and is just stuck out behind him. This is obvious because the sword is silver and the scabbard is black.
Other mistake: In the scene right after the team gets a Morse code message from Skinner, we see the holes made in the Nautilus. The one in the middle is smoking whereas the one in the back is not. If the ship was filling with water to the point that is was immersed due to the holes then whatever explosive components would be wet and extinguished. So by the time the Nautilus resurfaced, it should not have been smoking at all.
Revealing mistake: When the Nautilus' hull is breached by the explosives Gray has set, water rushes in with great force. The crewmen who get hit by the water do not get swept off their feet - as they should have - but instead keep on running. (01:07:10)
Continuity mistake: When Dorian Gray is shot with the machine gun, all the bullets are taken right in the gut, and the wounds are correctly shown in mirror-image when the back view of him is shown. However, the next shot of his front shows a couple of wounds in the shoulder, the biggest one being in his right shoulder at the very top, a wound which was not visible in the back view. (00:27:55)
