Tracey Ullman, comedian
Worth: £45m
The Simpsons began on the Tracey Ullman Show and have turned 43-year-old Ullman, who has a small stake in the cartoon, into a multi-millionaire. Her new show, The Trailer Tales, on America's HBO channel pays £600,000 a year. With syndication fees, adverts and an internet site, LA-based Ullman is worth £45m.
