Quite randomly, I was talking to a friend about movies her car-mad three-year-old might like, and I remembered my childhood and making airfix model cars just before knights and dinosaurs kicked in at around six or seven. I and my father glued a Darracq together and I know why. It was because of this film, which I loved as a child and which is, like everything else in the world, on YouTube.
And interestingly, even then, part of what I loved was the car and part was the glamour of the comic adversary's girlfriend, played by Kay Kendall. Who, I discover on looking the film up in IMDB, was calld Rosalind. Is that really where I fell in love with the name I would bear for the greater part of my life? I fear it probably was.
