If you’re of a particular age, the summer of 1989 holds special meaning for you. Specifically, you were almost certainly completely obsessed with Tim Burton’s Batman starring Michael Keaton and Jack Nicholson. The film redefined superhero movies for a generation, was a relentless blockbuster at the box office, and kicked off a wave of Batmania that left no merchandising stone unturned well beyond that fateful summer. But at the heart of that film is Nicholson’s stunning Joker performance. And one of the elements that makes it so memorable is how it marked the first time that the Joker was depicted in live action as a brilliant, but murderous chemist, just as he was in his very first comics appearance back in 1940. Joker spends the second half of the movie holding Gotham City hostage via “Smilex” a deadly nerve toxin that leaves its victims with a hideous post-mortem grin on their faces. These kinds of weaponized poisons are nothing new in the real world, but it’s the specific combination of effects that Smilex creates that make it so notable. We’re taking a look at the real world parallels, including some disturbingly high profile terrorist attacks that would have made the Joker proud. In the process, we also examine just how this movie’s approach to live action superheroics (and supervillainy) changed everything on the big screen.

But here’s a friendly reminder that we also covered one of Tim Burton’s other great films, the original Beetlejuice, on an episode of Does it Fly? recently, and you should absolutely check it out right here. And while the rules of the Joker toxin as we discuss them in this episode apply specifically to this particular Batman movie it’s been around in other media, too. Notably, a generally less lethal version made a few appearances on the classic Batman: The Animated Series, which is always worth a watch, especially now that gorgeous remastered versions are available on HBO Max. A few to consider that might scratch your Smilex-induced itch… “The Last Laugh” (S1E15) It’s primarily laughing gas here, but you know what it’s supposed to be. “Almost Got ‘Im” (S1E35) A case can be made that this is the best episode of the series, even though the Joker and his attendant poison only feature in one segment of it. “The Laughing Fish” (S1E46) Based on several classic issues of the comics (more on one of them down below) this is probably the closest you’ll get to the lethality of the original toxin in animated form.

VX Nerve Agent We’re bringing this up here in part because of the extraordinarily well-documented (and almost Joker-esque) assassination of Kim Jong-Nam in 2017. The murder was carried out using VX, a nerve agent and banned chemical weapon that is considered one of the most deadly and fast-acting out there. Let the CDC fill you in, because trust us, you want no part of this stuff. The Animal Kingdom and Joker Venom “There is no venomous animal on the planet that could do [everything the Joker Venom does]. Having said that, there are components of different animal venoms in the animal kingdom that could, in combination. My understanding of the Joker is that he’s quite a smart chemist, so it would be possible to extract the components from those venoms and put them all together.” More on this subject from Professor Jamie Seymour can be found here. Now, about that “recipe” (do not do this)... You’d want a little venom from the box jellyfish, known as one of the deadliest marine animals. A pinch of cone snail venom. And perhaps a dash of the blue-ringed octopus’ fatal defense mech
