Metal Gear Solid is a popular stealth action video game directed and written by Hideo Kojima for Konami. There have been talks of a live action movie adaptation of Metal Gear Solid since quite a while:
"Metal Gear Solid follows Solid Snake, a retired soldier who infiltrates a nuclear weapons disposal facility to neutralize the terrorist threat from FOXHOUND, a renegade special forces unit."
But unfortunately there's nothing concrete so far. Director Kurt Wimmer (who once brought us Equilibrium) was attached to the project and they were even aiming at a 2012 release. But It looks like the project has come to a halt:
The video game companies are very protective of their property and there are certain things a studio requires freedom-wise to market and distribute a movie effectively in a global marketplace and sometimes getting those two things to match up is really hard. And in the case of Metal Gear Solid, the agendas just….not because the parties weren’t amicable, it was just kind of impossible to get the agendas to match up."
The game has a strong following, so I don't worry much: I'm pretty sure they'll come to an agreement sooner or later and that we'll get to see a Metal Gear Solid movie in a not distant future.
