10 Terrifying Movie Monsters That Barely Appear

10. The Boar - Razorback

The unprecedented success of Jaws led to a splurge of copycats, involving piranhas, spiders, frogs, and rabbits. Unsurprisingly, many imitators didn't come close to matching Jaws, since they didn't emulate Steven Spielberg's "less is more" approach. Yes, a killer shark is frightening, but it leaves a bigger impact when it remains unseen, since viewers never know when the toothy fishy is going to pop out next.

One of the few Jaws clones that understood this concept is Razorback. Based on Peter Brennan's novel of the same name, the cult-classic is set in the Australian outback, where visitors and locals alike find themselves being tormented by a gigantic man-eating boar.

Effects artist Bob McCarron pulled out all the stops for this tusked tyrant, designing six animatronics, including one fully-sized model. Instead of showing off McCarron's impressive handiwork, the titular beast is kept off-screen or only partially seen. In fact, there isn't a full shot of the kaiju piggy at any point.

Luckily, this decision makes the brutish boar come across more like a mythical monster rather than an animal, accentuating the terror every time it shows up.
