Adams is best known as the author of The Hitchhiker's Guide to the Galaxy, which originated in 1978 as a BBC radio comedy before developing into a "trilogy" of five books that sold more than 15 million copies in his lifetime and generated a television series, several stage plays, comics, a computer game, and in 2005 a feature film.
