Piranha 3D bosses have started work on a sequel, after the film was a killer hit at the box office.
The Alexandre Aja film, which stars Richard Dreyfuss, Elisabeth Shue and Kelly Brook, took 10 million US dollars on its opening weekend in the States.
Heat Vision reports that, buoyed by this success, producers have already started work on a follow-up.
Producer Mark Canton said: "We are thrilled that audiences are not just loving Piranha 3D, but cheering for it. And it's fantastic that so many critics are really getting the movie and recommending it. We can't wait to get to work on the sequel."
