Back in 2008, it was announced that BioShock
would be getting a movie adaptation. Those plans never really materialized, and director Gore Verbinski has now explained why
"I couldn't really get past anybody that would spend the money that it would take to do it and keep an R rating. Alternately, I wasn't really interested in pursuing a PG-13 version. Because the R rating is inherent. Little Sisters and injections and the whole thing. I just wanted to really, really make it a movie where, four days later, you're still shivering and going, 'Jesus Christ!' It's a movie that has to be really, really scary, but you also have to create a whole underwater world, so the price tag is high. We just didn't have any takers on an R-rated movie with that price tag."
