An ad man angles to steal Don Draper from his firm by courting his wife for a modelling gig.
Jim Hobart: Anyone ever tell you you're a dead ringer for Grace Kelly?As compliments go, that's quite a doozy. Do you think January Jones heard that before Mad Men or is it all in that 50's princess styling?
Betty Draper: They used to.
Jim Hobart: You know what? Coca-Cola is deep into this international campaign right now. A European face like yours, like Grace Kelly's, might be a road we could go down. We could put a call out for a Grace Kelly 'type' but I don't think we'd come this close...
That "European face" they refer to was second generation American, born in Philadelphia with German and Irish heritage. Kelly's movie career was meteoric. She was famous by the age of 23 and retired by 27 after marrying Prince Rainer of Monaco. As with other A-Listers who are gone from the screen too soon (usually from death but occasionally from self-imposed retirement) she became legendary and continues to fascinate people. Including Mika, Madonna and numerous other songwriters
