 After the announcement of a film adaptation sparked a statement from the NAACP expressing concern that the transportation of Oompa-Loompas to Wonka's factory resembled slavery, Dahl found himself sympathising with the NAACP's concerns and published a revised edition.In this edition, as well as the subsequent sequel, the Oompa-Loompas were drawn as being white and appearing similar to hippies, and the references to Africa were deleted.Dahl later expressed regret over the original version, saying that his original intention of depicting Charlie as a black child was evidence that he was not racist.
