When a gigantic great white shark begins to menace the small island community of Amity, a police chief, a marine scientist and grizzled fisherman set out to stop it.
A brilliantly executed monster movie that launched the director's even more brilliant career.
On renewed viewing: it is remarkable how an old-hat exploitation story is surehandedly turned into an exciting and highly entertaining movie, perfectly balancing humor and shocks.
Halliwell**: "In the exploitation-hungry seventies this film took more money than any other. In itself, despite genuinely suspenseful and frightening sequences, it is a slackly narrated and sometimes flatly handled thriller with an over-abundance of dialogue and, when it finally appears, a pretty unconvincing monster."
Maltin****: "A rare case of a bubble-gum story...scoring as a terrific movie...Hold on to your seats!"
