Overview

• The creature, formally referred to in coverage as Trypanohyncha Ocellus, is a spherical, tentacled parasite that targets the eye area to control hosts.
• Episode 4’s widely discussed set piece used a real sheep on set with layered visual effects, a choice Hawley credits with making the moment far more unsettling.
• The design evolved from an early “eye with legs” concept to tentacled suckers that let it stick, propel itself and even launch across spaces.
• Cast members Samuel Blenkin, Timothy Olyphant and Babou Ceesay call it the show’s most disturbing creation, citing what they term a feeling of “genetic revulsion.”
• Hawley likens its relentless pursuit to the franchise’s facehugger, and new episodes continue Tuesdays on FX and Hulu through the September 23 season finale.
