Tracey Ullman (born 30 December 1959) is an English-born stage and television actress, comedian, singer, dancer, screenwriter and author. Critics have lauded her ability to shift seamlessly in and out of character and accents, with many dubbing her the "female Peter Sellers".
Her early appearances were on British TV sketch comedy shows A Kick Up the Eighties (with Rik Mayall and Miriam Margolyes) and Three of a Kind (with Lenny Henry and David Copperfield). After a brief singing career, she appeared as Candice Valentine in Girls On Top with Dawn French and Jennifer Saunders.
She emigrated from the UK to the US and created her own network television series, The Tracey Ullman Show (1987—1990) from which The Simpsons was spun off in 1989. She later produced programs for HBO, including Tracey Takes On... (1996—1999), for which she has won numerous awards. She returned to British screens in 2016 with Tracey Ullman's Show and Tracey Breaks the News. She has also appeared in several feature films. Her film credits include Plenty (1985), I Love You to Death (1990), Household Saints (1993) and Small Time Crooks (2000).
