The Magic Christian is a 1959 comic novel by American author Terry Southern (1924–1995) about an odd billionaire who spends most of his time playing elaborate practical jokes on people. It is known for bringing Southern to the attention of filmmaker Stanley Kubrick, who had received a copy as a gift from Peter Sellers, and subsequently hired him as co-writer for Dr. Strangelove (1964) when Kubrick decided to make that film a black comedy/satire, rather than a straightforward thriller. Guy Grand is an odd billionaire who spends most of his time playing elaborate practical jokes on people. A big spender, he does not mind losing large sums of money to complete strangers if he can have a good laugh. All his escapades are designed to prove his theory that everyone has their price—it just depends on the amount one is prepared to pay them.
Terry Southern (May 1, 1924 – October 29, 1995) was an American novelist, essayist, screenwriter, and university lecturer, noted for his distinctive satirical style. Part of the Paris postwar literary movement in the 1950s and a companion to Beat writers in Greenwich Village, Southern was also at the center of Swinging London in the 1960s and helped to change the style and substance of American films in the 1970s. He briefly wrote for Saturday Night Live in the 1980s. Southern's dark and often absurdist style of satire helped to define the sensibilities of several generations of writers, readers, directors and film goers. He is credited by journalist Tom Wolfe as having invented New Journalism with the publication of "Twirling at Ole Miss" in Esquire in February 1963. Southern's reputation was established with the publication of his comic novels Candy and The Magic Christian and through his gift for writing memorable film dialogue as evident in Dr. Strangelove, The Loved One, The Cincinnati Kid, and The Magic Christian. His work on Easy Rider helped create the independent film movement of the 1970s.
