There are three unicorns in the film: Elliot and Ridley's victim is the foal, while its parents, the mare and the stallion, attack the Leopolds in order to get their child back. Each came with its own set of inspirations.

Attorney Elliot (Paul Rudd) has a hot tub "meeting" with Shepard (Will Poulter) until the weird sounds start in a scene from "Death of a Unicorn."
