was recorded at AIR Studios Lyndhurst Hall, a converted church in London. "You could have recorded the same music in a studio in Los Angeles, and it would have been great, but there is something about the sound of that church studio," Howard remarked. "It's definitely more misterioso." Comic book references Filmmaker and comic book writer Kevin Smith felt Unbreakable was briefly similar to a comic book titled Mage: The Hero Discovered, written and illustrated by Matt Wagner. As in comic books, the main characters have their identified color schemes and aliases. David's are green and "Security" or "Hero", while Elijah's are purple and "Mr. Glass". The colors show up in their clothes, the wallpaper and bed sheets in their houses, Elijah's note to David, and various personal items. The people whose bad deeds are sensed by David are identified by an article of clothing in a single bright color (red, orange), to contrast them with the dark and dreary color scheme typical of the rest of the movie (but not of most comic books). Several scenes also depict characters through reflections or doorways, as if framing them in a picture similar to comic books.
