The writers originally drew up a list of ten British celebrities they wanted to appear in the episode. The Archbishop of Canterbury Rowan Williams (a fan of the show) was included in a draft of the script acting as a tour guide and showing some of his relatives around London. Williams had to reject the part due to other engagements. The script also included a role for a musician; the staff had hoped to get David Bowie or Morrissey for the part but nothing came together. David and Victoria Beckham were also originally sought to guest star in the episode, and would be seen bickering on the street. The idea was dropped after Blair agreed to guest star, and it was deemed that they were not famous enough (as a married couple) in the United States and so were not approached. Jean commented "We thought about it, we didn't ask. I've heard of him because my daughter plays soccer."
