Vin Diesel

Every actor has their own process. For me, I really need to stay in the pocket. So, if I'm on set and I'm in character, I'm not thinking like a producer. If I'm on set and I'm not in character, wardrobe and make-up, and I'm just coming on set for the moments that I'm not shooting, then I'm able to be the producer.

There's a darkness to Riddick that I think allows people to want him to do bad things because you know Riddick is going to do bad things: that's just the way it is. But I think that at his core, who he is and what he's fighting for is something that everybody can identify with.
