INDEXER NOTES (SPOILERS!)
Release—The <a href='https%3A%2F%2Fwww.imdb.com%2Ftitle%2Ftt0087788%2Freleaseinfo'>IMDb</a> lists a 12 September 1984 USA release in a manner that usually indicates a theater release, but the <a href='https%3A%2F%2Fwww.imdb.com%2Ftitle%2Ftt0087788%2Fcompanycredits'>credits page</a> doesn’t support that, and we’ve found no related promotional materials. So, we’re using the 1983 date of the earliest VHS that we’ve actually spotted on E-Bay. According to that same credits page, though, there may have been a 1980 Australian VHS.
