The marketing campaign for the movie The Descent coincided with the London bombings in July 2005. The distributor recalled posters that contained the word "terror" and re-released posters without that word. Having a 18 rating could have been a promotional technique, as people may have seen it as a challenge to watch a scary movie with such a rating. The movie's website featured a trailer, synopsis, cast list, gallery, message board, and "experience" section to generate excitement around the film.
