The BFG (short for The Big Friendly Giant) is a 1982 children's book written by British novelist Roald Dahl and illustrated by Quentin Blake. It is an expansion of a short story from Dahl's 1975 book Danny, the Champion of the World. The book is dedicated to Dahl's late daughter, Olivia, who died of measles encephalitis at the age of seven in 1962. As of 2009, the novel has sold 37 million copies in UK editions alone, with more than 1 million copies sold around the world every year.
An animated adaptation was shown on television in 1989 with David Jason providing the voice of the BFG and Amanda Root as the voice of Sophie. It has also been adapted as a theatre performance. A theatrical Disney live-action adaptation directed by Steven Spielberg was released in 2016.
