Without Chitty Chitty Bang Bang there would be no Truly Scrumptious, Caractacus Potts, and--unthinkable--none of the magical John Burningham illustrations in the book nor the terrific movie that more of the great ones worked on--including (deep curtsy here please, we are in the presence of such brilliance!) Roald Dahl.
So, thank you, Ian Fleming. Responsible for James Bond and Truly Scrumptious...now, who would've thought?
