The League of Extraordinary Gentlemen
This series is an absolute delight! Alan Moore and Kevin O'Neill initially came up with the idea of creating a "Justice League of Victorian England" but instead took the concept into a really different direction.
Mina Harker, from Dracula, is charged with assembling a team of "extraordinary" individuals to safeguard the interests of the British Empire. In the first volume, she gathers Captain Nemo, Allan Quartermain, Dr. Jekyll, and Hawley Griffin (the Invisible Man) to battle Fu Manchu and Professor Moriarty.
Future volumes incorporated elements from The War of The Worlds, John Carter, Dr. Moreau, 1984, James Bond, Emma Peel, and so much more. Each volume has numerous in-jokes and references that require multiple re-readings.
While not for everyone, it is an incredible read, especially the original mini-series.
And, yes, I do have a weak spot for the movie!
