According to this Variety report, Gore Verbinski has been confirmed as director for an upcoming Bioshock film.
“I think the whole utopia-gone-wrong story that’s cleverly unveiled to players is just brimming with cinematic potential,” said Verbinski. “Of all the games I’ve played, this is one that I felt has a really strong narrative.”
No release date was given for the project, although the piece does say, “Take-Two is developing a Bioshock sequel that will be released in 2009, almost certainly before the film comes out.”
