- Fake American: Linton's aide Bob Adriano is played by British actor Enzo Cilenti.
- Life Imitates Art: The MPs expenses scandal revealed two beautiful examples:
- Simon Foster avoids watching a hotel's porn channel for fear that it will "show up in the register of interests". Home Secretary Jacqui Smith's husband wasn't quite so careful.
- Lord Mandelson's claims for gardening expenses revealed he had been through a "diplomatic crisis" with a neighbour over neglect of his garden. His predicament was eerily similar to Simon Foster's as he struggled with Paul Michaelson (Steve Coogan) and his collapsing garden wall.
- Playing Against Type: James Gandolfini as Pentagon Dove General Miller.
- You Look Familiar: Anna Chlumsky, who plays Liza Weld, would go on to play Amy Brookheimer, another political aide character in Spiritual Successor series Veep (which was also created by Armando Iannucci).
