A film loosely based on the novel was made in 1968, with a screenplay written by Roald Dahl and Ken Hughes, directed by Hughes, Co-Director of Casino Royale. It was produced by Albert R. "Cubby" Broccoli, who had made five James Bond films previously. The film starred Dick Van Dyke as Caractacus Potts and Sally Ann Howes as Truly Scrumptious, an additional character who was not in Fleming's novel. Two actors from the Bond franchise were involved in the film: Desmond Llewelyn and Gert Fröbe, who played the parts of scrap-dealer Coggins and Baron Bomberst, respectively. A novelisation of the film was published by Pan Books in 1968, written by author John Burke.
