This quickly let us know that the character was a scheming, machine-gun-toting mastermind, which completely set him apart from all the other Jokers that we knew, especially Cesar Romero in the silly '60s Batman TV show. That is, other than the fact that Ledger wore Romero-Joker's mask throughout the entire bank robbery.

All evidence seems to point to the design of Ledger's clown mask being modeled directly on a scene from "The Joker Is Wild," an episode of the Batman TV series that also marked the first appearance of the Joker on the show. In the episode, Adam West's Batman tracks Romero's clown prince of crime to the Gotham opera company, where he's secretly performing an aria from Pagliacci, because back then that was as close as the Joker could get to being an actual killer clown (look it up). As you can see, the similarities between Romero's Pagliacci costume and Ledger's mask are undeniable.

And if anyone out there is wondering why Nolan even bothered referencing an old comedy series that was campier than a Boy Scout jamboree: While it's true that The Dark Knight was basically a superhero version of Michael Mann's Heat, the 1960s series is what has kept Batman alive in the public consciousness for decades, so despite its silliness, it still deserves all the respect it can get. The fact that the man who first brought the Joker to the big screen didn't respect the character enough to even shave off his mustache for the role should really be beside the point.

Try to put away your personal feelings for the movie or Johnny Depp and ask yourself: Does this man look anything like a classic pirate? I don't know; between the mascara, the bandanna, and the braided beard, he more resembles a goth hippie or something. And what's up with all the crap woven into his hair? Like this medallion here:

Walt Disney

Huh. That looks suspiciously like the Turkish star and crescent, but ... how? Call me crazy, but I faintly recall that Pirates of the Caribbean took place somewhere in the general vicinity of the Caribbean, so what is Jack Sparrow doing with an Islamic symbol in his dreads? Actually, if you subscribe to a Reddit theory, the coin and the rest of Sparrow's attire might actually be referencing the character's real-life Muslim inspiration, the infamous pirate Jack Ward.

Pier Francesco Mola

Jack Ward, also known as "Birdy," was a 16th century English pirate who terrorized the Mediterranean and eventually converted to Islam, taking on the name Yusuf Reis. For 15 years, Ward/Reis sailed the coast of North Africa, plundering ships and commanding hundreds of men, until he became something of a pirate celebrity. There have been songs and entire theatrical plays written about the man, and by all accounts his larger-than-life, drunken legend eventually inspired one of Disney's largest and sexiest cash cows.

The Islamic coin is just one clue, but there is more to support this theory. Jack Sparrow's headband, for example, does sort of kind of resemble a turban style worn in Islamic countries, plus the type of mascara he wears is known as kohl, which was primarily available in North Africa, where Jack Ward operated. Also, after hours of Googling, I discovered that sparrows are in fact birds, and "Ward" and "bird" both have four letters, and also Jack Ward was nicknamed "Birdy," ergo ipso facto randomus latinus, Disney is secretly converting children to Islam with the Pirates of the Caribbean movies.

Supernatural is a show that started out as a story about two brothers hunting monsters before ultimately focusing on how adorable Jensen Ackles and Jared Padalecki are together.

Warner Bros. Television

As the show slowly changed focus from horror to a kind of magical dark comedy, Supernatural eventually introduced a new leading character: Castiel, a demon-hunting angel from heaven who dresses like Columbo and whose main shtick is that he just doesn't get how the human world works. Here he is watching porn for the first time:

Warner Bros. Television

Yeah, it's kind of a lame joke, but Misha Collins plays Castiel with such a beautiful mix of childlike naivete and deadpan seriousness that you can't help but constantly laugh at his antics. In fact, Collins did such a great job with making the character his own that you can hardly tell anymore that Castiel was sort of meant to be a parody of John Constantine.

DC Comics, Warner Bros. Television

Non-comic book fans may not immediately get that reference, but they might remember the 2005 movie Constantine starring Keanu Reeves, which made film history by showing Shia LaBeouf getting brutally beaten to death. Well, that movie was actually loosely based on the excellent comic book series Hellblazer starring John Constantine: a chain-smoking antihero conman who investigates paranormal phenomena in an old trench coat and loose tie.

DC Comics

Eric Kripke, the creator of Supernatural, freely admits that Castiel's clothes are the same ones worn by the occult sorcerer with cancer. Thematically it does make sense, because Supernatural is about working-class guys taking out paranormal threats, which also happens to be the summary of pretty much every Hellblazer comic ever. Although, as far as I know, Constantine never once uttered the phrase "Hey, Assbutt!" so that's at least one thing Supernatural has over Hellblazer.

When I first saw The Powerpuff Girls on the old Cartoon Network, I really didn't get it. Then I discovered Japanese TV shows and the concept of satire, and suddenly everything clicked.

Cartoon Network Studios

The huge eyes, the giant monster fights, the Sailor Moon-esque juxtaposition of superheroism with the mundane problems of everyday life: That stuff made a lot more sense once I realized it all traced back to Japanese television. Sure, the satire wasn't especially clever or anything, but it made me feel smart when I first understood it all those years ago. Then I found out about the show's other super obscure references that I'd missed and felt stupid all over again. (The Powerpuff Girls turned out to be a real emotional roller coaster for me.)

Take Mojo Jojo, for example -- one of the series' chief antagonists who happens to be a superintelligent green monkey in go-go boots:

Cartoon Network Studios

At first glance, he looks like any other '90s supervillain, right down to the dome housing his cartoonishly oversized brain. But when designing the character, series creator Craig McCracken actually based his look on two characters from old Japanese TV shows that most Japanese people don't even remember. For instance, the green simian/space magician look was based on Dr. Gori, the main villain from the 1971-72 Fuji TV series Spectreman.

Fuji TV

Embodying the tokusatsu genre made famous by Power Rangers, Spectreman was a show about a super cyborg fighting the monsters created by the mad scientist Gori (think an illegitimate love child of Rita Repulsa and Dr. Zaius). The series also had a heavy-handed environmental message, which luckily never made it into The Powerpuff Girls, unlike the costume of the main hero from another Japanese TV series: The Kagestar.

Toei

Recognize the spiral pattern on his head? According to McCracken, the heroic Kagestar's helmet served as inspiration for Mojo Jojo's brain jar. Was it a subtle indication that there's still some good in the villainous monkey? Actually, considering that The Kagestar's main villain was a Nazi scientist called Dr. Satan, it's a safe bet that its influence on the cartoon didn't go past the wacky helmet design.

And since we're already on the topic of ripping off Japan ...

What's interesting about that scene is that, well, have you ever wondered why Liu's O-Ren Ishii was wearing a white kimono before Thurman's Beatrix attacked her? Sure, it looks stylish as hell, but in Japanese culture, white kimonos are usually reserved for priests, brides, and the dead, so it doesn't make sense for O-Ren to wear one ... unless she was planning to marry that crazy girl with the ball and chain before Thurman interrupted them, like in all those fan-fics I've written.

Miramax Films

There might be a perfectly rational explanation for her attire, and it's that it was a nod to the 1973 revenge flick Lady Snowblood, a tale about a 19th century woman seeking bloody vengeance on the men who killed her family, aka the backstory of Thurman's and Liu's characters. Tarantino never made it a secret that the movie influenced a huge portion of Kill Bill, right down to the costume O-Ren wore and her snowy battle arena, which mirror scenes from Lady Snowblood.

Toho

It might not be the exact same outfit, but the connection between the two movies is definitely there. On the other hand, the part where Thurman chops off the top of O-Ren's head all Hannibal style? That shit's entirely on Tarantino and whoever failed to send him to a child psychiatrist back when there was still time to help him.

The serial tells the story of a bunch of Marines taking on the costumed leader of a terrorist organization because he was trying to take over the world using light-based sci-fi weapons, and because Hitler still needed a few more years to classify as a credible villain. By now we've of course seen a million villains like the Lightning, but he allegedly started it all and inspired such famous baddies as Doctor Doom, Cobra Commander, and especially Darth Vader.

Republic Pictures, Lucasfilm

The famed Sith Lord has actually gone through many changes since the first draft of Star Wars. Initially he started out as a human general, then a Sith named Prince Valorum, before Ralph McQuarrie and George Lucas started playing around with the idea of a character that needed a respirator. This resulted in initial sketches where Vader resembled Dark Helmet from Spaceballs ...

Lucasfilm

... or something akin to a Sith version of a Stormtrooper:

Lucasfilm

The next sketches, however, show Vader much closer to how we know him now: sporting a slicker helmet, darker armor, and a proper cape, exactly like the Lightning in The Fighting Devil Dogs.

Lucasfilm, Republic Pictures

It's generally accepted that Lucas and McQuarrie used the Lightning as the basis for their final Vader design, probably thinking that, hey, the entire movie already started out as a ripoff of another old movie serial, so if they can't be original, they can at least be consistent.
