Oh, just a heads-up. The Star Wars-esque opening credit scroll, ending narration, and censored dialog was in the original UK theatrical release. The film was modified so that the movie could get a "U" rating (similar to a "G" rating in the US). They probably did this in hopes that the movie would last more than three weeks in the theaters. The extra footage on the Australian bluray was originally sourced from a professional videotape transfer of the UK print. The tag at the beginning of the the videotape is dated 12/3/1986, which was a few days prior to the theatrical release in the UK.
