Filmmakers working in all different genres love to include details in their movies that viewers are only likely to notice on a second or third viewing, and the horror genre is certainly no different.
But horror filmmakers are afforded a unique opportunity to sneak details past viewers given the genre's tendency to disturb and terrify those watching, often forcing them to focus their attention on a character in peril or terrifying monster in a specific area of the screen.
As a result, directors can deviously hide fiendish visual details in plain sight, such that fans will only likely notice them when they revisit the movie, free of the nervous tension and anxiety of that initial viewing experience.
These 10 horror movie details - from incredible foreshadowing to cute Easter eggs and everything else in-between - were all ingeniously concealed right in front of the viewer's face.
If you somehow managed to spot any of them on a first sit, then very well done, given that they didn't click for the overwhelming majority of people until a repeat viewing brought everything into clear focus...
10. Fonz's Leather Jacket - Scream (1996)
Wes Craven's Scream is a film so devilishly packed with sneaky details that fans are still discovering them to this very day, and one of the very best surely involves Henry Winkler's ill-fated Principal Himbry.
Moments before he's brutally murdered by Ghostface at school, he opens the closet in his office and, if you pay close attention, you might notice a familiar piece of garb hanging up on the left-hand side of the screen.
For a few seconds, a distinctive black leather jacket is visible that bears an uncanny resemblance to the very same, iconic jacket that Winkler wore while playing The Fonz on the legendary 1970s sitcom Happy Days.
It's incredibly easily missed given how fleetingly the item of clothing appears on screen, and also because viewers are likely focusing their attention entirely on Winkler himself throughout the tense sequence.
But in a movie as flagrantly, playfully meta as Scream, could any Easter egg be more appropriate in this moment?
