A spirited Disney family comedy, The Parent Trap (1961) follows identical sisters who meet at summer camp, switch places, and plot to reunite their estranged parents while derailing Dad’s new engagement.

Joanna Barnes portrays the sophisticated fiancée whose arrival raises the stakes for the girls’ scheme. Known for Auntie Mame and Tarzan, the Ape Man, she later cameoed in the 1998 remake as the fiancée’s mother.
