One Fine Day (film)  One Fine Day is a 1996 American romantic comedy film directed by Michael Hoffman, starring Michelle Pfeiffer and George Clooney as two single working parents, with Alex D. Linz and Mae Whitman as their children. The title comes from the 1963 song "One Fine Day" by The Chiffons, which is heard in the film. Michelle Pfeiffer served as an executive producer on the film, which was made in association with her company Via Rosa Productions. The film was nominated for an Oscar for Best Original Song ("For the First Time"). Melanie Parker is an architect and divorced mother to her son, Sammy. Her day gets off to a bad start when she is late to drop him off at school, due to the forgetfulness of fellow divorced father Jack Taylor, a "New York Daily News" reporter whose daughter, Maggie, is thrust into his care that morning by his ex-wife who leaves to go on her honeymoon with her new husband. The children arrive just a moment too late to go on a school field trip (a Circle Line boat cruise). Their parents are forced to accept that, on top of hectically busy schedules, they must work together that day to supervise each other's child. In their confusion of sharing a taxi, they accidentally switch cell phones, causing each of them, all morning, to receive calls intended for the other one, which they then have to relay to the right person. Melanie must make an architectural design presentation to an important client. Jack has to find a source for a scoop on the New York mayor's mob connections. Sammy causes havoc at Melanie's office with toy cars, causing her to trip and break her scale model display. In frustration, she takes him to a day care center (which is having a "Superhero Day"), where she coincidentally comes across Jack trying to convince Maggie to stay and behave herself. They create impromptu costumes for the children, using his imagination and her resourcefulness. She takes her model to a shop to get it quickly repaired. Having left for a meeting, she panics when she receives a phone call from Sammy about another child having a psychedelic drug. She phones Jack in desperation and asks him to pick up the children. He agrees, on the condition that she take over their care at 3:15 while he chases down a potential news source. While in Melanie's care, Maggie goes missing from a store, and wanders some distance down a crowded midtown sidewalk. Melanie breaks down in despair at the police station, files a missing child report, and then goes to a mayoral press conference to find Jack.
