People bounce the word "cinematic" around a lot when they talk about this game, so I knew with something that looked this fantastic, it was only a matter of time before someone started developing the concept into a live action film.
Thankfully, it looks like that idea might be on its way as Joystiq reports that there may be talks between the major players to bring the game to the big screen:
The studio hopes to bring the fallen aquatic utopia of Rapture to celluloid life through extensive use of green screen technology, an approach not dissimilar to Legendary Pictures' interpretation of 300. If the computer generated approach is deemed feasible and fitting, the focus can then shift to capturing BioShock's secondary (and uninhabited) characters. While it's not guaranteed to move beyond these early stages, this project has our full support, if only so we can see M. Night Shyamalan's face when he gets out-twisted.However, because Joystiq writer Ludwig Kietzmann doesn't mention WHICH studio is talking about this, its hard not to think that this sounds more like a "wouldnt it be cool if.." scenario. Rumors being what they are, there is a chance that if this rumor spreads far enough, it might prove to be the catalyst that could get the ball actually rolling on the project. If, on the other hand, there really is a movie being planned in some dark back room of a studio somewhere, I say go for it, guys. Its at least something different.
So far, the only information I've been able to find has been the Joystiq article, which was blogged by Film Junk, and then talked about through the Movie Blog. No other source seems to exist.
We'll try to dig around a little bit and see if we can validate this information a little better. Stay tuned.
