The Fantasticks (1964)

Widowers Amos and Ben plot to romantically unite Amos' daughter Luiss and Ben's son Matt by pretending to feud and forbidding the teens to associate, knowing they will resist their fathers' interference. As the two youngsters fall in love, the fathers plot to end the 'feud' by hiring a traveling showman to fake an abduction and allow Matt to 'rescue' Luisa.
