Which 1968 film had a screenplay co-written by Roald Dahl?

The 1968 film Chitty Chitty Bang Bang had a screenplay co-written by Roald Dahl.

The film was based on Ian Fleming’s 1964 children’s novel Chitty-Chitty-Bang-Bang: The Magical Car. Dahl worked on the screenplay with Ken Hughes and other credited writers. The resulting musical fantasy follows an eccentric inventor, his children, and a remarkable flying car.

Dick Van Dyke played Caractacus Potts, while Sally Ann Howes played Truly Scrumptious. The film was produced by Albert R. Broccoli, known for his work on the James Bond series, and directed by Ken Hughes.

Dahl’s screenplay credit is sometimes overshadowed by his children’s novels and his earlier Bond connection. He also received a screenplay credit for You Only Live Twice, released in 1967, but Chitty Chitty Bang Bang is the family fantasy associated with this question.
