 Cheri Montesanto-Medcalf, the make-up department head for The X-Files, was responsible for making Benrubi appear mauled and bloody. It took four hours to get all of his make-up on him, which included prosthetic appliances and a "head-to-toe" application of dirt and a thickening agent, giving him a "cracked and crusty" appearance. Benrubi wore the make-up for almost twelve hours straight. Costume designer Christine Peters was tasked with designing the outfits for Mulder and Scully. Mulder's outfit was composed largely of "Lacoste Izod alligator shirts, Dockers, Bass Weeguns," and Scully's outfit was "jeans and a sweatshirt [or] khakis and sneakers." Peters noted that Scully's outfit was harder to design because Scully's character has "a 'look' that she doesn 't want to give up."
