Director Steven Spielberg's biggest fear other than the appearance/performance of the mechanical shark was that cameras would catch sight of land. The reason Spielberg did not want land to be seen was because he thought the audience could envision the characters having the option of just running back to shore when in danger. He wanted to isolate the audience as much as the characters.
Cinema, short for cinematography, is often used to refer to the industry of films and filmmaking or to the art of filmmaking itself. The contemporary definition of cinema is the art of simulating experiences to communicate ideas, stories, perceptions, feelings, beauty or atmosphere.
