This movie's opening prologue reads: "No animals were mistreated or harmed during the making of this film. And no humans either".
The back cover sleeve notes of the book by Michael Winkler about the making of this movie, "Fahfangoolah! The Despised and Indispensable Welcome to Woop Woop" (2016), read: "Welcome to Woop Woop worst Australian movie of all time, or invaluable cultural artefact? With wild behind-the-scenes stories featuring Rod Taylor, Susie Porter, Johnathon Schaech, Barry Humphries, Stephan Elliott and a drunk clown; the mapping of links to other outback films; and a detailed argument for its place in the national canon, this companion is as vibrant and provocative as the movie that inspired it."
This Australian movie was based on the novel "The Dead Heart" by Douglas Kennedy. An Australian film actually called Dead Heart (1996) had been made and released just a year earlier.
The phrase "Woop Woop", according to the 'Urban Dictionary', is an "Australian term, a collective description for any destination outside your local area, ie: far away" whilst the Wikipedia Website state it "is an Australian term meaning far away from anything of interest, as in 'he lives out woop woop'. Equivalent terms include 'beyond the black stump' (also Australia), 'Boondock' (S. United States) and 'out in the sticks' (E. UK)", with Wikipedia adding, according to Tom Parry in 'Thumbs Up Australia: Hitchhiking the Outback' (2006), "the term is said to have been derived from the nickname given to men who carried fleeces in shearing sheds, after the sound they made as they ran around. It was also the name of a sawmill near the town of Wilga in South West of Western Australia that was abandoned in 1984", and further, according to 'The Dinkum Dictionary' (2010) by Susan Butler, Wikipedia states that "the term was being used in the early 1900s to describe a mythical outback town", which is what "Woop Woop" is in this movie.
One of the few times in movies when an actor or actress makes their first appearance in the movie after their name is listed in the end credits. Shane Paxton as Sonny and Bindi Paxton as Cher don't appear in the movie until a scene after the credits are done rolling, which takes place 15 years later.
