On the boundary-pushing ending: "They spent an increasing amount of money on less episodes, so it's gonna be much bigger in scale, the CGI. We're trying new things, experimenting with new camera techniques. I think we're trying to break boundaries and push past boundaries in these final two seasons."
On the best way for the show to conclude: "The worst thing would be to end without really pushing and trying new things. Even if it's a failure, at least trying to go out with a bang."
