Versus, crossovers and shared universes

With Marvel's impressive wave of success in theaters, it seems everyone wants to jump on the "shared universe" bandwagon, as if it was some kind of new thing. DC of course launched a Batman v Superman movie, followed by bigger crossover stories like Justice League. Universal announced a slate of monster movies set in the same universe, starting with a Tom Cruise-starring Mummy, and we even get a new King Kong movie as an introduction to an upcoming King Kong vs Godzilla. Hell, rumor has it that we will also see a Men in Black / 21 Jump Street crossover in the near future!

But none of this is really groundbreaking. At all. The original King Kong vs Godzilla was made in 1962, and was only the third episode in the Godzilla saga. Universal Monsters practically invented the concept of a shared cinematic universe in the 1940s, starting with the amazing crossover Frankenstein meets the Wolf Man. And even Marvel tried its hand at it as early as the 1980s, with the special episodes of the Incredible Hulk, co-starring Daredevil and Thor.

TV series have also been doing this for a long time: long before Flash and Arrow teamed up, viewers could watch The Pretender's Jarod visiting the Profiler squad, or Chuck Norris lending a hand to Sammo Hung in a Martial Law / Walker Texas Ranger crossover. And in the 60s, Batman and Robin crossed paths on-screen with the Green Hornet and Kato!

In fact, you don’t even have to be very old to remember a couple of relatively high-profile crossovers that hit the screens in the 2000s. Freddy vs Jason had been announced for a few years when it was finally released in 2003, and the clash of boogeymen was an entertaining revival for both franchises at once. Then in 2004, we got Alien vs Predator, followed three years later by its sequel Requiem. They kept the Aliens and Predator sagas alive during the long gaps between their respective official episodes.

But crossovers were invented way before film and TV entered our lives. Readers have seen Arsène Lupin meet Sherlock Holmes, or rather Herlock Sholmes (the name was slightly changed at Conan Doyle's request) in a couple of Maurice Leblanc’s novels. The encounter was brought to the screen in a German film serial as early as 1910, where the detective became Sherlock Holmes again.

Long before that, Ivanhoe joined forces with Robin Hood in Walter Scott’s novel Ivanhoe, and we can trace back the idea of crossovers to Homer’s tales of Gods and Heroes. Greek mythology was one of the first known cases of shared universes, with Zeus and Hera showing up in all kinds of stories – so it should come to no surprise that Italy would come up with a movie called Hercules, Samson and Ulysses in the 1960s!

Of course, Sherlock Holmes and Frankenstein have also had their share of cinematic crossovers: the detective met Jack the Ripper on screen twice, and Frankenstein was confronted to Dracula, Santos, Jesse James and numerous other characters. But Sherlock Holmes vs Frankenstein? Not yet. We're working on it, remember?

2009: Zorro vs Sherlock Holmes

While filming the last William Boquet, two major things happened: I moved in with the woman whom I would eventually marry, and I decided to write a new ambitious script about two iconic characters. Sherlock Holmes vs Frankenstein? Nope, I wasn't there yet. The initial project was Zorro vs Sherlock Holmes.

I've always been fond of time-defying characters: Robin Hood, Dracula, the Three Musketeers... And Zorro of course. Before I even thought of being a writer-director, I wanted to be an actor. To play Zorro. And before that, I wanted to be Zorro himself. So the concept of having him and Holmes meet and fight seemed exciting. Both swordsmen, one of them cultivating mysteries, the other solving them. Of course the timeframe wouldn't allow Sherlock Holmes to meet Don Diego de la Vega in his prime, but he could easily meet his grandson – which was the setup for this script.

Holmes and Watson, in their early years (not long after A Study a Scarlet), travel to California in order to unmask a dangerous criminal who calls himself Zorro. Of course, they eventually find out that he's fighting the good fight, against a corrupt local government. Together, they retrieve a treasure that had been unfairly confiscated from the Indian people, and they bring down the evil military in an epic final swordfight. Or something like that. I was really excited about this project. I had re-read the whole Sherlock Holmes Canon, as well as Johnston McCulley's original Zorro novel. I had spent hours watching films about both characters, in order to sort out what made them interesting.

But despite having a beginning and an end, the story was hard to put together. Why would the evil military call Sherlock Holmes to help them? Why would Zorro need him to overpower the bad guys? How could the viewer be excited by Holmes unmasking Zorro, when his identity would already be known to him? And if we hide it from him, by having several “potential Zorros”, then how will the viewer care for this character? And most of all: how is there going to be a foe charismatic enough to stand in front of two legends? 

John Neville as Holmes

A lot of those questions derived from the fact that Holmes and Zorro are both positive characters, who can't really be opposed unless one of them loses the audience's sympathy. It's like having a movie called Batman vs Superman (oh wait!), you know that they will eventually join forces. So unless you have a great villain, someone that the viewer already knows, it kind of falls flat because your heroes won't be fighting a big threat. I didn't want to bring Moriarty into the plot, it was against my rules – which rules, you might ask? Watching and reading non-canonical Holmes stories, I have observed that most of them (if not all!) featured one or more of the following characters: Irene Adler, Mycroft Holmes and/or Professor Moriarty. I ended up finding it very annoying, since these characters are only featured once or twice over the course of 60 stories written by Conan Doyle. Hell, Moriarty is often believed to be Sherlock's recurring nemesis, when he's only the main antagonist in one short story (and one that seems to have been hastily written by Conan Doyle in order to kill off his detective). Watson doesn't even get to meet him in person! As for Irene Adler, a lot of versions want us to believe that Holmes and her have been romantically involved, to the point where they're sometimes supposed to have a child together. But in A Scandal in Bohemia, Watson clearly states: “It was not that he felt any emotion akin to love for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise, but admirably balanced mind.” In fact, several stories have Holmes fall in love, with Adler or someone else, when that goes against all 60 canonical adventures! Bottom line is: I decided that if I was to write a Sherlock Holmes story, I wouldn't use Irene Adler, Mycroft or Moriarty.

While I was struggling with the plot, looking for a way to make it worthwhile (without letting Holmes or Zorro become the other's supporting character), I stumbled upon the information that Zorro wasn't public domain property. It belonged to the Zorro Estate, who probably wouldn't allow the character to be used in a crossover with another hero. In the 60s, Zorro had been confronted to Maciste, the Three Musketeers, and even naked women in a few soft-porn movies, but the copyright-holders had straightened the line in the 90s with “mainstream” productions such as the Antonio Banderas movies, the book by Isabel Allende or the recent musical show. So here I was, stuck with a story that didn't quite work and a character that possibly could be an obstacle to making the film even if I sorted out the plot. So I started toying around with the idea of replacing him with another mysterious avenger, probably the Scarlet Pimpernel – which would have moved the plot to France.

But one day, lightning struck. It was the end of February, 2010. I was sitting in a movie theater, in front of a French comedy that didn't have my full attention. Suddenly, I thought of Sherlock Holmes vs Frankenstein. It didn't have anything to do with what I was watching. It was just a title that popped up. During the last 30 minutes of the screening, the main elements of the script came together in my head. When the credits hit the screen, I left the theater (which I usually don't do, I like to stay until the very end – even for movies I don't like!) and rushed home, where my 6-month pregnant wife saw me go straight to my desk, take a pen and paper, and write down the outline for this new script. It all felt so obvious, that I couldn't understand why it hadn't occurred to me earlier: Sherlock Holmes and Watson would travel to Germany, not California or France. And they would have to unmask a mad scientist, one who would have created a giant monster. It made perfect sense: Holmes was the hero, the monster was a menace and the identity of the mad scientist was the mystery to solve. Now I knew the direction I was headed. I just didn't realize how long the journey would be.
