I pitched Jay Hunt the opening scene (prime minister, middle of the night, he's woken up...). She paused, and then she laughed. She was very intrigued and all that, and then she said, "Does it have to be a pig?" So we went through various options: Could it be a supermarket frozen chicken? A giant wheel of cheese? A pig seemed just the right level of absurd, but then when he walks in and there's actually a pig there, it's awful.

Often the ideas in the show start out as ideas that make you laugh - outrageous "what if" ideas. I wanted an outlet for doing those.

When you look at things like social media, that's an immensely powerful tool that I'm all in favor of. I think it's amazing. It's a powerful tool, and it's one that we're, as a species, still grappling with learning to use.
