12. The shark roar – Jaws (1975)

In Jaws, almost by accident, the climactic explosion of the shark, with technical difficulties involving the shark's animatronic form, did not go off exactly as intended. Added humor and grit to the scene with Roy Scheider's quip: "Smile, you son of a—" as he tried to smile, balancing the tension and triumph. That moment of malfunction was turned into an opportunity, converting an unplanned challenge into a memorable cinema moment that cemented the film's legendary status in thriller history.
