For the original 1984 Ghostbusters movie, the rating depends on the country and release version, but the most commonly cited ratings are:

  • United States (theatrical and home video for many years): PG (Parental Guidance suggested). This reflected 1980s standards, when PG covered more intense content than it usually does today, and the PG‑13 rating had only just been introduced later in 1984.
  • Later UK classifications: 12A for cinemas and 12 for DVD/Blu‑ray, mainly due to moderate sex references and some stronger content than is now considered suitable for a universal PG family film.
  • Australia (film classification): PG, with consumer advice such as “mild supernatural themes and coarse language, some scenes may scare young children.”

So if you are asking “what is Ghostbusters rated” in general, it is best described as a PG/12‑type movie depending on the modern local board: originally PG in the US and several other regions, but often upgraded to 12/12A in more recent reclassifications because of language, innuendo, and some scary or suggestive moments.
