Despite only earning approximately $800,000 in its home country of Australia, Bait 3D was a sizable success overseas, making over $24 million in China alone. It also made $2 million in Italy. As a result of its international success, Darclight Films announced that the film will receive a sequel, however, no further films have yet been produced.
Three different Pomeranians were used in the movie to play Heather's dog, Bulli - one for swimming, one for barking and one for running.
Three animatronic sharks were used for filming. Although director Kimble Rendall wanted to entirely avoid using computer-generated imagery, the budget necessitated its use in some scenes.
The film began shooting in Queensland, Australia in September 2010 and wrapped just prior to Christmas 2010. On January 3, 2011, the post-production was moved to Singapore where it continued for several months.
First ever Singapore-Australian feature film co-production.
