In 2003, and after eight months of negotiations, then-British Prime Minister Tony Blair became the only head of government to appear in The Simpsons during season 15's 'The Regina Monologues'. Blair recorded his part in ten minutes at his Downing Street home. A character played by Frasier star Jane Leeves, as well as Sir Ian McKellen and JK Rowling were all encountered by the Simpson family during their trip to the UK.
