Don't know whether this has been noted before, but about a third of the way into "The Pink Panther", there is a snow scene where the countess and her chauffeur drive up to a staged fight between David Niven and his butler. Their car is either a Rekord or an Olympia, '63 or '64 vintage (movie released in '64), head on shot with
O P E L prominently displayed on the nose.
