Piranha
Speaking of razor-sharp, but in a more literal sense here, this 1978 creature feature kicked off a mini-franchise and still holds up as one of the more memorable Jaws rip-offs of its day. Gremlins’ Joe Dante directs, Roger Corman produces, and the cast (which features Invasion of the Body Snatchers’ Kevin McCarthy and Black Sunday’s Barbara Steele) is surprisingly star-studded. And it goes without saying any time you can unleash a school of mutant piranhas, good times are guaranteed to follow. Watch on Peacock.
