According to Deadline Hollywood Dimension Films has locked in a director and writers and will race to get a Piranha 3D sequel up and running quickly to hit theaters by late August, 2011. Dimension has set John Gulager to direct and Saw 3D scribes Patrick Melton and Marcus Dunstan to write Piranha 3 DD, the sequel to last summer's toothy fish fest that found itself earning the ire of Cameron. The filmmaker cited it as an example of the hasty 3D conversions, while he was barnstorming for Avatar. That led to a sharp -- and lengthy -- rebuke from Piranha 3D's producer Mark Canton. For the sequel, Dimension's Bob Weinstein has reassembled the team behind Feast, the Dimension horror film that served as a season of the TV show Project Greenlight. The director and writers got their starts on that low-budget horror film. Gulager went on to direct two Feast sequels while the scribes moved on to write four installments of the Saw franchise. They recently set an updated version of the classic anthology series The Outer Limits at MGM. Making a late summer date will be difficult, but not impossible, if the writers nail the script in the next four weeks.
