If there is a fantastic universe so vast in the world of comics, that it would make the Marvel and DC universes a simple galaxy, it would be the League of Extraordinary Gentlemen.
Written by Alan Moore (who you already know from works like Watchmen, From Hell and V of Vendetta) and drawn by Kevin O'Neill (a #comics veteran, who participated in the British publisher 2000 A.D. in works such as Marshal Law, Nemesis The Warlock Judge Dreed).
He mixes the books of Jules Verne, H.G. Wells, Mary Shelley, Robert Louis Stevenson, Arthur Conan Doyle, Edgar Allan Poe, H.P. Lovecraft, William Shakespeare, George Orwell, Miguel de Cervantes, Mark Twain, Fritz Lang, Jonathan Swift, Bram Stoker, H.R. Haggard, Edgar Rice Burroughs and "dime novels" from the United States and some light nods to popular culture that someone with a good eye can detect, like a reference or mention, you have this universe.
When reading their vignettes, it aroused in me the curiosity to look for the titles they mention, such as the American dime novels with the Steam Man of the Prairies, Captain Mors, the stories of Juan de Mandeville, the Blazing World and the chivalric stories from the Middle Ages.
And wanting to know more about the protagonists, I read King Solomon's Mines where the adventurer Allan Quatermain appears, 20 thousand leagues under the sea with Captain Nemo and his underwater boat the Nautilus, the Invisible Man by H.G. Wells and the strange case of Dr Jenkyll and Mr. Hyde, I still have to read Dracula where Mina Murray (or rather Mina Harker) appears, Moore and O'Neill unintentionally instilled in me the reading of each book.
Although some remember it for the film adaptation of 20th Century Fox, a film that was destroyed by critics and the audience, and even Alan Moore himself disowned it, which meant his departure from the world of comics and the last participation of the actor Sean Connery (the original James Bond), for someone who saw the film without having any idea that it was based on this universe, a concept like this would have been a brilliant idea, to create a universe where all the literary works from the epic of Gilgamesh or the Iliad passing through the novels of Jules Verne or H.G. Wells until the events (say in that case) 2001 a space odyssey would be incredible.
Speaking at this time when the big film production companies are going through a kind of "crisis of creativity", the protests of the scriptwriters and actors and the fact of making remakes of films (a.k.a. Disney).
Speaking at a time when the big film production companies are going through a kind of "crisis of creativity", the protests of screenwriters and actors and the fact of making remakes or sequels of films (Disney, Warner) that in the end ended up being disappointing , I'm not asking for more Star Wars, Toy Story or other stories whose plot we already know (like superhero movies), I'm asking for good ideas like the one Moore and O'Neil brought us.
