    17 Famous Movie Lines That Were Geniusly Improvised

    “You're gonna need a bigger boat" started as an inside joke!

    Improvisation is a sword most actors learn how to wield. However, only the ones who've mastered the art can come up with an absolutely killer line on the spot, often making for some of the most memorable movie moments.

    Here are 17 iconic movie lines actors came up with on the spot:

    1. Roy Scheider improvised the line "You’re gonna need a bigger boat!” in Jaws because it was an inside joke among the cast and crew.

    The joke started with the barge nicknamed the S.S. Garage Sale, which carried all of the filming equipment and was steadied by a singular, tiny boat. 

    Writer Carl Gottlieb told the Hollywood Reporter, "[Richard] Zanuck and [David] Brown were very stingy producers, so everyone kept telling them, ‘You’re gonna need a bigger boat.’ It became a catchphrase for any time anything went wrong — if lunch was late or the swells were rocking the camera, someone would say, ‘You’re gonna need a bigger boat.'”

    2. The scene in Black Panther where M'Baku leads the Jabari men in grunting at Everett Ross for speaking out of turn was entirely Winston Duke's idea.
