The movie was the first of two consecutive ghost comedies that Bill Murray made over the course of two years. He starred in [Ghostbusters II](/category/10889/Ghostbusters-ii) (1989) the year after this one. Wikipedia states, "the film was marketed with references to Ghostbusters (1984), which had been a great success four years earlier." In the U.S., the tagline was, "Bill Murray is back among the ghosts, only this time, it's three against one".
