 "Oliver Twist" tells the story of an orphan forced to live in a workhouse headed by the awful Mr Bumble, who cheats the boys who work there out of their already low pay. Oliver decides to escape to the streets of London, where he meets a thief called Fagin, played by Sir Ben Kingsley, who leads him into a world of crime. Several of Dickens' books have been made into films and television series, including 2002's "Nicholas Nickleby" and 2000's "David Copperfield." And several versions of "A Christmas Carol" have entertained audiences for years. 

In his novels, Dickens wrote about several important issues. He talked about the Poor Law Amendment Act of 1824 in "Oliver Twist"; the French Revolution in "A Tale of Two Cities"; and helping the poor in "Hard Times." One of Dickens' best-known books is the first Christmas book he wrote - "A Christmas Carol" (1843), about a mean man.
