Effects

The Ceti eel shots used several models, overseen by visual effects supervisor Ken Ralston, who had just finished creature design for Return of the Jedi. He tied a string to the eels to inch the models across the actors' faces before they entered the ear canal. The scene of a more mature eel leaving Chekov's ear was simulated by threading a microfilament through the floor of the set up to Koenig's ear. The scene was filmed with three variations, which Ralston described as "a dry shot, one with some blood, and the Fangoria shot, with a lot of gore." Footage of a giant model of Koenig's ear was discarded from the theatrical release due to the visceral reaction it elicited in test audiences.
