The famous line "You're gonna need a bigger boat" originated from the movie "Jaws" (1975). It was spoken by the character Martin Brody, played by Roy Scheider. The line has become one of the most iconic quotes in cinema history and is often used to refer to a situation where a problem or challenge is much larger than anticipated. "Jaws," directed by Steven Spielberg, is a thriller film about a great white shark terrorizing a beach community, and the line is delivered when Brody first sees the enormous size of the shark.
