Trivia

The crawlers were designed by Paul Hyett , a makeup and prosthetics creator. Production designer Simon Bowles said that the crawler design had started out as "wide-eyed and more creature-like", but the design shifted toward a more human appearance. Crawlers originally had pure white skin, but the look was adjusted to seem grubbier. The skin was originally phosphorescent in appearance, but the effect was too bright and reflective in the darkened set, so the adjustment was made for them to blend in shadows. The director barred the film's cast from seeing the actors in full crawler make-up until their first appearance on screen. Actress Natalie Mendoza said of the effect, "When the moment came, I nearly wet my pants! I was running around afterwards, laughing in this hysterical way and trying to hide the fact that I was pretty freaked out. Even after that scene, we never really felt comfortable with them." The crawlers reappear in The Descent: Part 2 (2009), a sequel by Jon Harris with the first film's director Neil Marshall as executive producer. For the sequel, Hyett improved the camouflaging ability of the crawlers' skin tones to deliver better scares. According to Hyett, "Jon wanted them more viciously feral, inbred, scarred and deformed, with rows of sharklike teeth for ripping flesh." A charnel house was designed for the crawlers as well as a set that the crew called the "Crawler Crapper". See more
