Katie Featherston and Micah Sloat in Paranormal ActivityPARANORMAL ACTIVITY

It's not often that you witness an image in a horror movie (or in any movie, really) that you instinctively recognize as iconic. The last one I can think of in the scare-flick genre would probably be Heather Donahue in The Blair Witch Project, with her wool cap, her nose running, and her mouth out of camera range as she videotapes a final, tearful apology. (Seeing that shot for the first time in 1999, you knew it was one that would endure - and be parodied ad nauseam.) But we now have a new addition to the Iconic Image Hall of Fame thanks to Paranormal Activity, which, like Blair Witch, was filmed on a shoestring budget, and which features a shot, like that of Donahue, that will no doubt be instantly identifiable for generations of horror-movie fans.
