When FX and Disney+ launched Alien: Earth late this summer, fans expected xenomorphs, facehuggers and chestbursters. What no one expected was a sheep possessed by an alien eyeball staring out of its skull.
⚠️ Spoiler warning: This article contains details from Episodes 4 and 6 of Alien:Earth.For this new story within the Alien universe, rather than relying solely on the classic Xenomorph, the series has expanded the menagerie with a host of unsettling new organisms. We’ve seen grotesque, giant ticks (dubbed the Leech or Species 19), and even flies that can chew through metals, alloys and minerals, upping the danger for the seemingly indestructible hybrids at the story’s core.
The standout species, however, is Species 26. Also known as the “Eye Midge” or "The Eye parasite", this tentacled eyeball whose iris can split into multiple smaller eyes or come together as one single, disturbing, gaze, has quickly become one of the show’s most talked-about creatures. Even surpassing the almighty Xenomorph.
And with the season finale just around the corner, let’s explore how the production and FX team brought this cute nightmare to life.
“THE EYE” PARASITE
The Eye parasite, officially classified in the series as Trypanohyncha Ocellus, went through several design iterations before making its debut. As showrunner Noah Hawley explained to The Hollywood Reporter, it initially had just legs and was very fast. But it was VFX supervisor Jonathan Rothbart who suggested a major upgrade: suckers.
“[The suckers] was a really great upgrade for the original conceit where before, it just had to run as fast as it could at you. Now it can fly (...), propel itself, stick to you and you’re basically trying to fight it off”, Noah Hawley, showrunner
The showrunner also drew a direct comparison with the iconic facehugger. Whereas it forces its way down the throat, the Eye parasite takes control through the eye socket. “It just felt like it’s designed to play into that genetic revulsion”, he added.
Beyond its weird biology, the Eye parasite is characterized by its behavior: it is smart, cunning... and unnervingly observant. Not like the other aliens, who are hunters, always looking for food. As for why a sheep, Hawley told SciFiNow:
“The sheep was just what I typed in that moment. You know goats have a sort of satanic presence in our stories; sheep are just kind of daft and smelly, but in an innocent kind of way. And I really liked the idea that, much like Monty Python did with the rabbit, we might take the sheep and make people look at it in a very different way”
HOW THEY BROUGHT IT TO LIFE?
Though there’s no full VFX breakdown released yet, interviews with cast, crew and articles give us a good map of what was done, including a clever blend of practical effects, puppetry, CGI and even creative camerawork.
A singular POV. Because the Eye has one globe but multiple shifting irises, the cinematographers gave us a point of view using an in-camera kaleidoscopic filter, letting the audience “see” through its fractured, hyper-observant vision. Director of Photography Colin Watkinson (one of the series’ DPs, alongside David Franco, Dana and Bella Gonzalez) introduced the filter on set. According to Ryan McGregor, the show’s main unit Digital Imaging Technician, they usually “shot wide open on the V-Lite Lenses with a bit of nose grease on the filter”.
On set. To help actors and cameras find their marks, the crew used a practical eyeball prop as a stand-in, as showed in a featurette. This was part of a larger philosophy of keeping something physical in the frame, even when CGI would later replace it.
“You always want as much in camera as possible, even if you're not gonna use it because it gives you so much information and gives the actor something to act around, and gives the DP something to light around, and gives the director something to direct around. So, it's a huge part of the process”, VFX supervisor Jonathan Rothbart
In post. The puppet was only a starting point. In postproduction, the Eye was fully replaced with CGI and that’s where it came alive. How it moves, how it launches itself, how it observes before striking: all decisions made by the team of animators behind this creature. In captivity, they sometimes played it as cute, small and light, with its tentacles pressed against the glass. But when it's free? It's a violent, fast and strong little creature that aims for your eye socket, only to fall back into silence once inside a host, watching everything with its shifting irises.
“I always try and think about why this creature does what it does. I need to know why it's doing these choices it's making. I try to treat it in a directorial way, because in doing that, it can help inform me on how I want to have him animated to act in the scene”, VFX supervisor Jonathan Rothbart on FX’s official podcast
Victoria the sheep. For early shots, the production filmed with a real sheep, nicknamed Victoria. To keep her stock-still and staring, her handler scratched her belly with a green-gloved pole, as explained in Polygon. Once infected, Victoria was swapped for a Wētā Workshop animatronic double, which was uncannily similar to the real thing. CGI then enhanced the iris splitting and other alien touches.
“It was quite limited in movement, but it was able to do these creepy things. I mean, it looked creepy to begin with, as it was just standing still, and it was able to cock its head and chew very slowly and do little weird things with its eyes”, Ugla Hauksdóttir, director of episode 6, on the animatronic
In humans. A similar method was used when the Eye infects Schmuel, an engineer aboard the USCSS Maginot. Prosthetics handled the initial look, while CG refined the alien eye itself and possibly blended transitions between live action and digital augmentation.
Ultimately, it was the blend of animatronics, live performance, and digital artistry that made the Eye parasite feel real. And while fans still wait for full VFX breakdowns, one thing is clear: the Eye Midge has earned its place in the Alien bestiary.
