Hayley Mills and Maureen O’Hara shared one of the most magical and most enduring films in the history of Disney cinema when they made The Parent Trap together in 1961 — the story of twin sisters separated at birth who engineer the reunion of their estranged parents with a mischievous ingenuity that audiences have never stopped finding irresistible across sixty-five years of continuous love for a film that somehow manages to feel timeless in every era it finds a new generation of viewers.

Maureen O’Hara played the mother with the particular combination of warmth, steel, and effortless elegance that was her signature across a career that made her one of the most beloved actresses of Hollywood’s golden age, and Hayley Mills played both daughters with a quicksilver charm and a completely unaffected naturalness that remains one of the most remarkable child performances in studio history. The working relationship between them has always been described in the carefully diplomatic language of professional courtesy — mutual respect, pleasant memories, the comfortable retrospective warmth of two people associated with something beloved — and for sixty-five years Hayley Mills has maintained that version of the story with the discretion of someone who understands what certain films mean to the people who love them and what the responsibility of that love requires. At 79, having outlived Maureen O’Hara by a decade and having arrived at the stage of life where the reasons for certain silences no longer outweigh the value of a certain kind of honesty, Hayley Mills has finally said something about the woman she shared that set with that the official version of the story never quite contained — and what she has chosen to reveal, in the careful, considered way of someone who has been thinking about how to say it for a very long time, reframes the relationship behind one of the most beloved films of the twentieth century in ways that are surprising, human, and completely impossible to unknow.
