For the crew and cast of the flick it has to be "R, a hard R." They don't want it to become a silly light humoured romantic comedy romp in Rapture.
"We're working trying to make it. The problem with BioShock was: R-rated movie, underwater, horror. It's a really expensive R-rated movie," the Pirates of the Caribbean director, Gore Verbinski, explained to .
"So we're trying to figure out a way working with Juan Carlos to get the budget down and still keep so it's true to the core audience, you know? The thing is it has to be R, a hard R," he said, talking about director Juan Carlos Fresnadillo.
Has the 'swing and a miss' Prince of Persia: The Sand of Time at the US box office poured huge doubt over the BioShock movie making a splash?
"No, I think BioShock's a rare one because it's actually a great story," he said.
"Me? I don't want to make movies based on videogames, but BioShock's the one Oedipal, crazy kind of -- it's just got really good bones, and we're really trying to figure out a way to make it work." The budget is where the problem lies - damn accountants.
"We don't want to dumb it down, we don't want to make it PG-13. We want to keep it really edgy, and it's a huge bill," continued Verbinski.
What if Juan Carlos ups and goes from the project? Will Verbinski take the helm? "We're really down the road with Juan Carlos and right now it's really a budget thing and how to keep the integrity and keep it a Hollywood movie because it could balloon."
"It's a lot. Our first budget was extraordinarily high and we're working on it," he said, seemingly dodging a straight answer - meaning it's doomed if Juan Carlos quits?
