Christopher Haden-Guest, 5th Baron Haden-Guest (born February 5, 1948), better known as Christopher Guest, is a British-American screenwriter, composer, musician, director, actor and comedian. He is most widely known in Hollywood for having written, directed and starred in several "mockumentary" films that feature a repertory-like ensemble cast. In the United Kingdom, he holds a Baronial peerage, and has publicly expressed a desire to see the House of Lords reformed as a democratically-elected chamber. Despite initial activity in the Lords, his career there was cut short by the House of Lords Act 1999.
