The sharks in this film are real, and the footage of the sharks was filmed in the environs of Port Lincoln on the Eyre Peninsula of South Australia, just off the state's Spencer Gulf, at the Neptune Islands.
The movie is based on true events that happened during the 1980s off the coast of Townsville in far northern Queensland, Australia.
With careful research and extensive technical planning, a streaming team was assembled to execute a day-long live internet stream, offering viewers the chance to not only watch numerous scenes being filmed, but to also ask questions of the cast and crew via real time webcam interviews and online chat.
Of sharks, the film's writer-director-producer, Andrew Traucki, said: "Sharks and shark attacks are a huge part of the Australian culture and how the rest of the world perceives us. It's not uncommon to hear of friends or relatives that arrive from overseas but are too scared to enter the ocean because they believe they'll be taken by a shark. Mention sharks at a party and everyone will have a story or a take on them. Indeed if you can believe the website digital or search engine Google, sharks are one of the most searched for terms in Google from within Australia. The animal is synonymous with this country and yet Australians have never made a feature film about them. The American's took one of our true stories and turned it into a very successful film called 'Open Water' [2003]. For 'Jaws' [1975] they came to Australia to get their shark footage [at Dangerous Reef in South Australia], but here in Australia we've never made a feature film about one of our most notorious cultural ambassadors. Well that's now going to change."
Shot in five weeks.
