It's important to continue to change and evolve in the way that the comics change and evolve.

Now it's been fifteen years, nine games, and an enormous blast to undertake. If it were my choice, I would do this role forever. To hear anyone else's voice coming from Snake's battered throat, makes me a little ill, to be honest.

On the lower budget pictures, you go overtime more, you're sort of scrambling for the shots and cobbling together more ideas at the end.

When you're playing a tough guy, all the other guys want to be tough right back at you and it amps them up.

To turn a human being into a part-canine or lupine creature takes a good deal of artistry and money.

Zombies - obviously they're doing it in a much more expansive way on The Walking Dead - basically, what you used to do is you put a bunch of goo on an actor and have them shamble towards you, and it's a very effective creature. It always has tremendous impact, just that feeling of death coming for you; that's universally accepted.

While the storytelling in games is getting so much better, you look at something like Grand Theft Auto V, which I thought was really beautifully written, it doesn't really need a movie because it is a movie. So I think you need a unique game - you either need an incredibly talented writer and director to come in and put together an amazing vision, or you need a game like Metal Gear, which is very cinematic, has a huge amount of history behind it, but whose cinematic experience is very different from what you'd get in a theater.
