In October 2003, the Chicago Tribune reported that the yellow Rolls-Royce is owned by Neal Kirkham of Saratoga, California, USA.
The Rolls-Royce used in the film was a pale blue 1930 Phantom II Sedanca de Ville, which M-G-M technicians covered with 20 coats of yellow paint; a few coats of black were added to the top of the hood, the roof, and the wings.
