The League of Extraordinary Gentlemen by Alan Moore and Kevin O'Neill is reportedly getting a new film adaptation. Unlike the previous one, which heavily deviated from the plot and themes of the original story, the new film will hopefully draw more from the comics' epic plot. This in turn could allow the filmmakers to introduce some truly unique characters.
If the upcoming League of Extraordinary Gentlemen film pulls more from the overall series instead of just adapting the first volumes, then it should definitely find a way to include gender-fluid swashbuckling immortal Orlando.
Orlando was introduced in The League of Extraordinary Gentlemen: Black Dossier (by Alan Moore, Kevin O'Neill, and Bill Oakley) which included the biography of their life. Like the rest of the cast, Orlando is derived from other famous fictional characters but Moore and O'Neill drew inspiration from multiple sources for Orlando. This included Virginia Woolf, French Medieval legend, and the Orlando the Marmalade Cat children's book series. Within the series, Orlando was born thousands of years before the present day to a blind seer. While their sibling was gifted with the power of prophecy, Orlando inherited a form of omnisexuality that transformed them between a male and female body every few years.
Sold into slavery and eventually forced to flee, a runaway Orlando was exposed to the liquid flame in the city of Kor, rendering them immortal. Orlando spent the following centuries traveling the world and participating in historical events, including fighting in the Trojan War, serving at the behest of King Arthur, and falling deeply in love with Sinbad. Eventually meeting the powerful magician Prospero in the 16th century, Orlando accompanied him to England and became a member of the very first League of Extraordinary Gentlemen. Orlando became more important in the latter half of the series, joining up with Quatermain and Mina to form a new team (and begin a polyamorous relationship) while fighting MI5, the Harry Potter inspiried Antichrist, and other fearsome forces.
Orlando consistently proves to be a clever and formidable warrior throughout the series. They are a complex take on an immortal that doesn't shy away from the loneliness and loss that in some ways define the character. Orlando has outlasted empires and yet finds themselves repeatedly fighting in wars. Despite embracing a flighty personality and getting themselves caught in an endless cycle of serving as a soldier for kings they'll outlive, they recognize the "pointless" nature of war. In response, Orlando embraces an at times foolhardy enthusiasm for life, almost locked in a perpetual state of immaturity.
Orlando is also unapologetically flirtatious with everyone they meet, and has stacked up an epic list of partners over the years, giving them the confidence most characters lack. Orlando's immortality also makes them a useful tie to the legacy of the League and the overarching plots that eventually come to dominate the story. This is especially true of their relationship with Mina, which ends up being a consistent beat until the end of the series.
Orlando is a fascinating character, and a big-screen adaptation could be an exciting chance for a more gender-fluid performer. Orlando's fluidity is a major aspect of the character but not what solely defines them, and having a gender-fluid action hero with thousands of years worth of experience as an adventurer would be a great addition to the canon of characters young people still discovering their true selves could look up to. While Orlando might not truly appear in the earliest stories in the series, introducing them to the story a bit earlier could give the new film adaptation of the series a powerful additional character.
