Jaws  

Jaws is arguably one of the greatest horror movies of all-time. Steven Spielberg’s ability to frighten audiences for a long duration of the film without even showing the titular shark is a genius tactic that builds suspense.

The crew is preparing for the menace they are facing when Roy Scheider’s character gets a sudden up-close look at the beast. He slowly slinks back and with the iconic cigarette dangling from his mouth, improvises the line, “You’re gonna need a bigger boat.” It’s also a great dig at the cheap film producers for them not springing for a larger ship.
