Hot off the $10 million opening weekend for "Piranha 3D," Dimension Films announced Monday (August 23) that a sequel is already in the works.

"We are thrilled that audiences are not just loving 'Piranha 3D,' but cheering for it," producer Mark Canton said in a statement. "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."

We've been following the blood- and breast-filled production since its humble beginnings, back when we visited the Lake Havasu, Arizona, set where co-star Paul Scheer bragged to us that the film's blood content would likely break records.

"Over 600 gallons of blood were used in this movie so far, and we're not even done," Scheer told us. "This is gonna be the most boobs and blood in any motion picture of all time."

Despite the film's seemingly campy nature — complete with the cast's cheeky Funny or Die video, in which they ask the Academy to consider "Piranha 3D" for a Best Picture Oscar nomination — the 1978 original film and its 1981 sequel "Piranha II: The Spawning" launched the careers of respected filmmakers Joe Dante, John Sayles and James Cameron.

And if those established pedigrees aren't enough, director Alexandre Aja knows what it takes to get moviegoers into theaters. "There's going to be 3-D double-D boobs!" he laughed when we talked to him earlier this summer. "I want to know exactly how many different girls' boobs are in the movie. I think it's a lot. I think blood-wise, I have to get the final number, but we are beyond anything you can even imagine."

With a current rating of 81 percent Fresh on Rotten Tomatoes, the film has struck a chord with critics as well. MTV's own Kurt Loder called the film's effects "top notch," "fluid" and just plain fun. "The thrills here may be traditional, but they're still actually thrilling," he wrote.

The Associated Press' Christy Lemire gushed about the film: "Run, don't walk: 'Piranha 3-D' is hilariously, cleverly gory. Mere words cannot describe how awesomely gnarly 'Piranha 3D' is, how hugely entertaining, and how urgently you must get yourself to the theatre to see it. Like, now."
