Yeah, but Bioshock already has all the story elements it would take to make a flick. They just need to make it believable for that time period and we're good. The game itself never really did that. The visual settings do, but there isn't much explanation for how Ryan got a whole city up in the middle of an ocean all by himself. Heck, they wouldn't even need to get to the downfall of Rapture since it feels like the creation will take up enough time and money to think up. They just have to get creative.
