This movie was originally planned to be first episode of a 12-part Australian Broadcasting Corporation horror series entitled 'Fright'.

This film's short-feature running time of 54 minutes is because it was originally intended to be a TV pilot episode when filmed.

Legend has it that some of the rats seen in the film escaped into other parts of the Australian Broadcasting Commission (ABC)'s studio and bred there. It is said that staff would not go to certain parts of the studio in fear of the rats from this movie.

This was the first theatrically released horror movie of the new wave of Australian cinema during the 1970s.

To promote this movie, lead actor Norman Yemm walked down the Pitt and George streets of Sydney wearing a sandwich board advertising this film and with an axe over his shoulder embellished with fake blood.
