Dimension Films must be counting on it, as today they issued a statement announcing plans for a sequel is already underway, with director Alexandre Aja returning. Producer Mark Canton had this to say...
“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.”
Aja has previously said that Thailand, specifically the annual Full Moon Party, could be a possible setting for any Piranha sequels. Whether or not that pans out still remains to be seen as no writer has been officially attached as of yet.
