Every iconic character can be traced back to some original form of inspiration, and for the Joker, fitting with the Clown Prince of Crime’sambiguous origins, there are several to choose from, withChristopher Nolanand his team opting to partly baseHeath Ledger’s interpretation onFritz Lang’s 1930s crime epicThe Testament of Dr. Mabuse. Speaking towards crafting the revelatory performance,Christopher Nolan toldEmpirethat he made his brotherJonathan Nolanwatch the film before writing the character, with concern established over stepping up to fans' expectations and the benchmark established byJack Nicholson in Tim Burton’s versionof one of the most instantly recognizable rivalries since Cain and Abel. Contrary toearly expectations, however, Ledger’s version of the Joker is widely known as THE Joker in the current pop culture canon, thanks in no small part to myth making surrounding Dr. Mabuse himself in Fritz Lang’s 1933 epic.

The Joker’s comic book origins can be traced as far back toConrad Veidt’s star-making performance inThe Man Who Laughs, proving just how much the character has been molded bythe classic cinema of the 1920sand 30s. However, while there was never any shortage of great Joker stories, screenwriterDavid S. Goyercommented in theEmpireinterview thatthere was one thing missing from the portrayals of the character that he was familiar with: “I like the Burton films a lot, but the one bone to pick with film, television, anything: I just never felt that the Joker wasscary. Chris and I wanted the Joker to bescary. Which is what led toThe Dark Knight.” As a result, Christopher Nolan decided to draw from “the earliest of the comics,” every panel of which screamed both menacing and over-the-top. Enter Dr. Mabuse, the original King of Crime, whose own mysterious origins and methods of dominating the world around him proved vital in selling the Joker as a true agent of chaos.

Dr. Mabuse Shares Many Similarities With ‘The Dark Knight’s Joker

Withso many versions of the Joker to draw from, whether it’sthe goofballor the psychopath, the biggest task thatThe Dark Knighthad laid out in front of it was picking a lane. WatchingThe Testament of Dr. Mabuse, it becomes clear where much of the character’s tendencies as acriminal mastermindcame from. The film follows the unraveling of a gargantuan criminal conspiracy orchestrated by an incapacitated Dr. Mabuse (Rudolf Klein-Rogge) from the safety of his cell in an insane asylum. The incarcerated criminal now writes several books worth of illegible gibberish, only for the investigating police to discover that they are in fact coded messages, and that through disguise, subterfuge, and hypnosis,Mabuse has enacted his master plan for an “unlimited reign of crime,” where chaos and anarchy trump all. Sound familiar?

Dr. Mabuse Is Similar to Other Iconic Batman Villains — Not Just the Joker

The psychology of Mabuse is where things become especially mirrored. Uncharacteristic to criminal supervillains of the time, Mabuse was among the first to be described as a genius and as totally insane in the same breath. He exhibits the kind of ‘super-sanity’ that allows him to enactschemes that you’d need to callAdam West’s Batmanto come in and deal with, yet does so in a colorless manner that roots it in the real world. Mabuse’s plans include attacking chemical plants, poisoning the water supply, creating a counterfeit currency, and that’s only scratching the surface.His methods of crime act as a who’s who of Batman villains to follow, whether it’sthe Scarecrow,the Riddler, orBane. But most like the Joker, he establishes his iron grip on his city while remaining largely behind-the-scenes. It’s not the fact that the Joker can make a pencil disappear that makes him so frightening, but the fact that he’s just as dangerous locked inside of a cell as when he’s roaming the streets of Gotham City.

The influence of both Dr. Mabuse and Heath Ledger’s Joker endure to this day. Most recently at the Golden Globes, accepting a Best Director win forOppenheimer,Christopher Nolan recalled the work of Ledger, stating that the last time he was on that stage, he was accepting the award on his behalf. Even winning an award for himself, however, he’s still accepting it on behalf of the work that his entire team put in, and though he may have been their leader,all a director can do is push everyone to bring their A-game in the hopes of crafting the best work of art that they can.Fritz Lang may have been a dangerous tyrantbehind the scenes, and Nolan himself is no stranger tobizarre practices on-set, but it’s this ability to articulate their visions and spearhead a team of massive talents towards one specific goal that’s made them two of the greatest directors of all time.
