The first film adaptation of one of Roald Dahl's works, Willy Wonka and the Chocolate Factory, is released
The first feature film version of Charlie and the Chocolate Factory is released as Willy Wonka and the Chocolate Factory in 1971.
Featuring a screenplay written by Roald Dahl, and with Gene Wilder playing Mr Wonka, the film would go on to become a cult classic, although the process of its creation was fraught - as Roald's biographer Donald Sturrock says in Storyteller, among other things Roald "regretted that the producers had chosen neither Spike Milligan nor Peter Sellers to play the role [of Willy Wonka]."
1971 also saw the American release of The Night Digger, a film starring Roald's wife Patricia Neal and with a screenplay by Roald himself. In the UK, it was known as The Road Builder.
