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.
First ever Singapore-Australian feature film co-production.
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.
