This Collider.com article hears from Hollywood director Guillermo Del Toro about his current slate of projects, including inSane, his upcoming game, of which he says he's working directly with the developers at Volition, "and every week we have a conference [call] where we exchange ideas about the design, the gameplay, about the models." He also talks of the learning experience this represents for him:

I came to videogame development with a lot of humility because I didn’t want to come in with the attitude of, “Oh I know how to make movies, therefore I know how to make videogames,” which is a big mistake. I came in trying to learn a new medium because I think it’s going to be very useful for me as a storyteller.

With a videogame, you don’t have to solve one screenplay, you have to solve 20 screenplays, because you are giving the player the illusion of free will. If the character kills another character or destroys a building, the game goes one way; if the character doesn’t, it goes another. It keeps you very nimble.

I think that’s the biggest, and the most fun, lesson I’ve been getting. We’re being really, really nasty in the game. We’re really trying a lot of stuff that I don’t think would even fly in the movies. It’s still two-and-a-half or three years away, though, because videogame development is so long.
