The only reason the shark aka Bruce never appeared early in Jaws is because it rarely worked. If I remember correctly our first sight of the shark was in the lagoon when he eats the scout leader. But the kicker was when it popped up in the gotta get a bigger boat scene. Still love watching that movie. I remember going to see it at the movies 4 times and waiting in line forever each time. It was a big deal of a movie back then and there wasn't videos to rent later.
