You never want to lean on things that you did knowing that it was like a back-up parachute. You don’t want to pretend there’s a back-up to that back-up parachute. And yesterday’s approach doesn’t necessarily work today. That’s what I really enjoy – that double sliding scale Spock Chess thing. How do you do it? How did you ever do it? How did you do it before, and how are you going to do it next time? I think, ultimately, it comes down to the very self-deprecating Mr. Whedon, who is more exacting on himself than he could ever be on anyone else. But he’s specific and in charge and I found him enjoying himself a bit more this time while simultaneously holding himself to a higher standard. You can’t do the same thing, only smaller, not as cool. There’s that other trap – where it’s, “Everything is bigger! Better! Do you know how many gigabytes we used in the opening sequence? How many terabytes?” Ultimately it comes down to that.
