#9: “You’re Gonna Need a Bigger Boat”
“You’re gonna need a bigger boat,” famously delivered by Roy Schneider as Chief Martin Brody in Jaws, wasn’t a spur-of-the-moment idea. Originally an inside joke among the crew, this line perfectly encapsulated the film’s tension with its massive shark antagonist.

Despite a tight budget forcing the production to use a small boat, the phrase “You’re gonna need a bigger boat” became a humorous way to comment on set mishaps, from late lunches to technical issues. Schneider’s impromptu use of the line during filming cemented its legacy.
