I honestly can’t remember any other time this has happened to me, but I think the movie is actually BETTER than the books it is based on! It takes the best elements of Volume 1 a smidge from Volume 2, but the plot is totally different from either in the end.
Allan Quartermain (Sean Connery) if the first recruit after armed men attack him in Africa. Though he is on shaky ground with queen and country he answers the call and finds himself in London face-to-face with a mysterious agent for the crown known only as “M” (Richard Roxburgh). He meets the other members so far assembled like Captain Nemo (Naseeruddin Shah), Mina Harker (aka Mina Murray, played by Peta Wilson) and Rodney Skinner (Tony Curran), who is this version of the League’s Invisible Man.
They set off together to bring a reluctant Dorian Gray (Stuart Townsend) into the fold, where they are ambushed by The Phantom and his men. Luckily, Tom Sawyer (Shane West) of the CIA had infiltrated the henchmen and saves our heroes with his sharp shooting. After Quartermain and Sawyer capture Mr. Hyde/Dr. Jekyll (Jason Flemyng) in Paris the League is complete, and M sends them to Venice to save a group diplomats at a peace summit. The plot thickens when they find out there is a traitor in their midst, and the string of explosions bringing Venice down around them is only the beginning.
This movie is really fun and I love watching it. The effects are special and the action is well-paced. It doesn’t break a whole lot of new ground and besides Nemo’s car it doesn’t really have as many gadgets as one might like to see in their Steampunk, but I love seeing a world where all of these literary heroes (and anti-heroes) get to team up.
There are a few very important differences from the books to the film, some of which were brilliant and some were disappointing. First, Dr. Jekyll gets to play a much larger role in the movie than in the books, and with the addition of Gray and Sawyer the League feels bigger and more complete. Mina is given both a larger and smaller role at the same time, because in the books she is the clear leader of the League but in the movie she is not only a scientist but force to be reckoned with on the battlefield. I think she was subsumed as leader mostly because of the desire for a Sean Connery type to play the part of Quartermain. The League didn’t have quite enough “flash” to it for the big screen, so they needed a more dynamic male lead to be opposite Mina (especially if they had hopes to pursue a romantic storyline in a sequel). There aren’t that many silver fox action heroes out there, so I think they took advantage of having the right actor for that kind of part rather than keeping to the book’s portrayal of Allan as a skinny, wrinkly drug addict.
All in all, I would say the changes that they made helped the movie to feel full and rich in a short amount of time when they didn’t have two books to work with.
