You might have seen rumours of Christian Bale doing a Metal Gear Solid film. Someone spoke to him about it: he isn't.
From an MTV interview:
MTV: Metal Gear Solid, is this something you've ever talked about doing as a film?
MTV: Are you a video game fan?
MTV: What do you play?
Bale: That. Metal Gear Solid.
MTV: You play it?
MTV: How many hours does that suck out of you on a weekly basis?
Bale: You know what, no, I've kinda devoted my time to more constructive things of late. You know?
Such a happy chap. Thanks, Kotaku.
