2. Jaws (1975)
Director: Steven Spielberg
Stars: Roy Scheider, Robert Shaw, Richard Dreyfuss, Lorraine Gary, Murray Hamilton
Vacation destination: Amity Island
Nothing says summer vacation like losing a limb to a bloodthirsty Great White, right? Spielberg's masterpiece managed to taint every carefree summer pleasure with fear: skinny dipping, wading in knee-deep water, and carefree boat rides all become fate-tempting pastimes with his machete-mouthed predator lurking in the waves.
Jaws may have demolished our ability to enjoy treading in murky beach water, but it also destroyed the box office as the highest-grossing film at its release, and established itself as the quintessential summer blockbuster. Many have tried to capitalize on the fish phobia Spielberg unearthed (see: Discovery Channel's Shark Week) and countless movies have unsuccessfully followed in its footsteps (see: Shark Night 3D), but none have managed to make the prospect of a midnight swim more unappealing.
