Trivia: A video game from Sega in 1972 was called Killer Shark, considered the first video game in the horror genre. The object of the game was to shoot at a giant shark with harpoons. This game can be seen in the seaside arcade in the movie.
Trivia: Often touted as the first "summer movie;" what this refers to is the now-typical marketing practice of doing most of the advertising before the film's release to build up hype ahead of a big nationwide opening weekend (at the time most movies opened in a limited number of markets to build a reputation). By the 80s this model was followed by big tentpole "summer blockbusters," but nowadays is the norm for the majority of studio releases year-round.
Answer: Although the 1995 documentary "The Making of Jaws" claims that the shooting star was real, the fact is that the shooting-star background effect is a Steven Spielberg trademark in most of his films (first noticed in "Jaws," but also appearing in "Close Encounters," "E.T. The Extraterrestrial," "Indiana Jones and the Temple of Doom," "Saving Private Ryan" and others). Spielberg has always had a fascination with shooting stars, dating back to his childhood, and he works them into almost every film.
