The Simpsons: 15 Celebrity Appearances You Might Have Missed

3. Eddie Izzard

Episode: To Surveil With Love (Season 20) In one of the most bizarre castings, Eddie Izzard landed the role of the Queen. Not only does Izzard play Her Royal Highness, but he also voices a security consultant named Nigel Bakerbutcher who installs CCTV around the town for 'security' purposes. It transpires that the footage is actually being used for a British reality TV show that the Queen loves. But why? Because everyone's favourite little weirdo Ralph Wiggum reminds her of her own son...the future King of England, Prince Charles, who is also voiced by Eddie Izzard. Tress McNeille and Maggie Roswell have also played 'Lizzie' in The Simpsons, but a brave move by the producers saw Izzard take on the role.
