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.
