Richard Roxborough played Sherlock Holmes in the Hound of the Baskervilles movie. In the LXG movie, Richard Roxborough acted as Moriarty, Holmes's arch enemy.

American agent Tom Sawyer was created in the film so to attract an American audience.

In the scene where M indroduces Quatermain to the League there are numerous pictures of previous leagues. One appeared in the comic and features Dr. Syn, Lemuel Gullivar (From Gullivar's Travels) and the Scarlet Pimpernel. Another painting includes Robin Hood.

Captain Nemo's chauffeur introduces himself by saying, 'Call me Ishmael.' This is the opening line in Moby Dick. An obvious literary reference.

During a pan shot (I believe it's just before Quatermain's car pulls up at the League's headquarters) near the beginning of the film, a poster can be seen on one of the brick walls with several names on it. The names are those of the creators of the original comics series: Alan Moore, Kevin O'Neill, Ben Dimagmaliw and Bill Oakley.

The mask that Richard Roxburgh wore as the Phantom distorted his voice so much that he had to redub his dialogue for the film's release.

One of the paintings of former Leagues include the Three Musketeers as well as their companion, D'Artagnan.

All of the League are fictional characters from Victorian novels.

Never in Oscar Wilde's story was Dorian Gray invincible, as is depicted in the film. Nor did looking upon his picture kill him. Dorian regularly stood in front of the painting, observing the degradation of his soul. He was only killed when he tried to destroy the picture.

Nemo being an Indian (both in the original graphic novel and in the movie) was derived from the original version of Jule Verne's Mysterious Island. In 20,000 Leagues Under the Sea, however, Nemo was Polish, and in the course of re-publications over generations (and in previous movies), Nemo was turned into a European.

When "M" is relating the history of the past LXG to Quatermain, over his shoulder hangs a painting of a previous team. In the foreground you can see the visage of Dr Syn, the Scarecrow of Romney Marsh from the book and Disney film of the same name.

When we first see 'M' he takes a cigarette from a case that features a picture of a harlequin. This exact same case/image was used in the comic to introduce the character of Campion Bond, M's assistant.

No wonder Quatermain knew of Moriarty - in his cabin on the Nautilus (the scene where he evicts the invisible Skinner) you can see a copy of Strand Magazine, the magazine that first published the exploits of one Mr. Sherlock Holmes.

Never in Robert Louis Stevenson's original short story was Mr Hyde larger than Dr Jekyll. He was considerably shorter and therefore Jekyll's clothes hung loosely from him. Also, Jekyll never needed a potion to become Hyde after the first time. The change became involuntary and ever more frequent. Hyde needed the potion to *change back* to Jekyll.

Some of the film's complicated photography required Townsend to shoot a scene backwards. He said,"It's a very quick clip where I steal Jekyll's vial. Basically, they wanted to end the shot with the hand on the vial. And because they have to be so specific, it's such a fast speed shot and it just stops exactly, I couldn't do it normally. I had to walk into the room backwards and then go all the way back and pick up the vial backwards so that the camera could actually focus on that one. That was strange."

Dorian Grey's residence was set up in an old WW2 sugar beet factory. In fact, some fermenting materials were still there, and in order to prevent the stench from flooring cast and crew, the compost had to be covered with chemicals.

Originally, it was intended that the part of Campion Bond was to be played by Roger Moore - both to have two ex-Bonds in one movie, and as an obvious pun to the character's name. But the idea was eventually dropped.
