As sharks start attacking people in a holiday resort, police chief Roy Scheider has to decide what to do, whilst being given advice from shark expert Richard Dreyfuss and fisherman Robert Shaw. Steven Spielberg produced a great film for its shocks and effects for the time, that was a hugh box office success. One of the most memorable highlights of the film is the haunting and very effective John Williams score, which is one the defining pieces of film music. There are good performances from the three lead characters and these are enhanced by good production and a good script. This is a very good example of how the use of music can enhance a film and build the drama and suspense of a scene.
