Jaws 2 is a 1978 horror–thriller film directed by Jeannot Szwarc. It is the first sequel to Steven Spielberg's 1975 Oscar winning classic Jaws. Although there would be two further films in the series, Jaws 2 is generally regarded as the best of the sequels.[1] Set four years after the events of the original film, another great white shark arrives on the shores of Amity Island. After a series of deaths and disappearances, police chief Martin Brody (Roy Scheider) suspects that the culprit is another shark. However, he has trouble convincing the town's selectmen. He has to act alone to save the group of teenagers, including his two sons, who meet the shark during a sailing expedition.
Like the first film, the production was troubled. The original director, John D. Hancock, proved to be unsuitable for an action film and was replaced by Szwarc.[2] Scheider was also unhappy during production and had several heated exchanges with Szwarc.[3]
The film's tagline, "Just when you thought it was safe to go back in the water...", became one of the most famous in movie history and has been parodied and homaged several times.[4]
