The eighth novel of The Dresden Files finds even the monsters getting in on the Shout-Out game, as a plague of fear-eating fae shapechangers assault a horror-movie convention. But with black magic afoot in Chicago, the creatures are after more than just mortals' terror, and Harry may find his own Council just as dangerous as any splatter-flick scaremonger:
Having to crawl out the Blue Beetle's window after it's run off the road spurs Harry to reference The Dukes of Hazzard to Murphy and himself.
The phobophages mostly take on the role of generic horror movie monsters. One, however, is quite obviously the Xenomorph from Alien. Others are Captain Ersatzes of Jason, Chucky, and Pumpkinhead.
The Suburban Slasher film series, featuring the Reaper, are a very thinly-disguised lawyer-friendly version of the Friday the 13th film franchise, complete with hockey mask, ten sequels, and Death by Sex.
Fighting the Xenomorph, Harry quotes Aliens repeatedly:
A pleading phone call from Nelson forces Harry to weigh The Cold Equations of survival, in choosing whether to go help Molly's boyfriend or remain at the convention. As in the short story, the needs of the many attendees outweigh Nelson's solitary dilemma justifiably in this case, as the young man's fears are a product of his psyche being tampered with, not an external threat.
Molly asks Harry if there's mud on her boots, and he points out that it hardly matters considering she'd dressed like Frankenhooker.
When Michael reacts to how she's dressed, Harry paraphrases Jesus:
"Let he who hath never stonewashed his jeans cast the first stone."
Deliberately invoked by Harry wielding Summer-Fire against a Scarecrow-like Fetch:
Rawlins insists anyone sneaking past him without him noticing would have to be a Jedi Knight or something.
Harry himself gets to pull the mind-trick on Detective Greene, complete with lines paraphrased from Obi-Wan. (He doesn't break the Fourth Law to do it, because Greene just had his bell rung and is suggestible enough for it to work without any magic.)
Molly's littlest sister Hope is nicknamed "Hobbit".
As a group, Molly still calls her young siblings "Jawas".
Detective Greene, according to Harry, is the sort of skeptic who watches Nova and subscribes to National Geographic.
Harry doubts that Mab could be acting erratic as Lily claims, citing how Shakespeare called her "constant as the northern star".
He quotes Shakespeare directly to the Scarecrow, but it either doesn't recognize or doesn't appreciate the reference.
He also "cries havoc", a la Julius Ceasar, while blasting the Xenomorph-phobophage.
