Jean and Denise Lavergne erroneously believed themselves to be the couple in The Kiss, and when Robert and Annette Doisneau (his older daughter and also his assistant at the time) met them for lunch in the 1980s he "did not want to shatter their dream" so he said nothing.
The couple in Le baiser were Françoise Delbart, 20, and Jacques Carteaud, 23, both aspiring actors.
