Matthew Richard "Matt" Lucas (born 5 March 1974) is an English comedian, screenwriter, singer, and actor best known for his acclaimed work with David Walliams in the television show Little Britain; as well as for his portrayals of the scorekeeping baby George Dawes in the comedy panel game Shooting Stars, Tweedledee and Tweedledum in Alice in Wonderland, and the roguish innkeeper Thénardier in the musical Les Misérables.

In May 2007, he was placed seventh in the list of the UK's 100 most influential gay men and women, by British newspaper The Independent.

Lucas was born in Paddington, London, the son of Diana (née Williams) and John Stanley Lucas (1944–1996), who ran a chauffeuring business. Lucas was raised in an observant Jewish family, with some of his British-born mother's family having fled Nazi Germany. His family were members of Edgware and District Reform Synagogue. Lucas grew up in Stanmore, Middlesex; he has an older brother, Howard. He has had alopecia since his childhood, which in interviews he has inconsistently attributed to various events, including a delayed reaction to a car accident at the age of four. He lost all of his hair when he was six years old. Lucas' father died of a heart attack aged 52, in Brent, Greater London.
