Columbia had negotiated 50% of the box-office revenues or 90% of gross after expenses, depending on whichever was higher. Since the latter was the case, the studio received a 73% share of the box office profit, an estimated $128 million. The main cast members each received percentages of the gross profits or net participation of the film. While figures do not exist for all involved, a 1987 report estimated Murray alone had earned between $20–$30 million from his share. Detailed box office figures are not available for territories outside North America, but it is estimated to have earned approximately $53 million, bringing "Ghostbusters" worldwide total to $282.2 million. That year saw the release of several films that would later be considered iconic of the era, including: "Gremlins", "The Karate Kid", "The Terminator", "A Nightmare on Elm Street", "Romancing the Stone", and "The NeverEnding Story". This was the first time in box office history four films, including "Ghostbusters", grossed over $100 million.
