Jean-Marc Clément, Yves Montand, a billionaire, learns that he is to be satirized in an off-Broadway revue. Curious and a little wary, he heads to the theatre where he first spots Amanda Dell, Marilyn Monroe, rehearsing the Cole Porter tune My Heart Belongs to Daddy. The scene is playful yet charged, and through a quirk of fate the director mistakes him for an actor who could plausibly portray himself on stage. To keep an eye on the spectacle and to understand the world that will soon mock him, Clément volunteers to join the production, adopting the name Alexander Dumas as his stage alter ego. What begins as a dare quickly thickens into a genuine curiosity: he finds himself drawn to Amanda, and his presence nudges him closer to the life he previously observed only from a distance.
As rehearsals proceed, Clément’s fascination with Amanda sharpens into jealousy, especially toward the onscreen persona she enjoys with Tony Danton, the character played by Frankie Vaughan. He watches Amanda’s attention tilt toward the actor, even as she is ostensibly helping Tony reach stardom. In a bid to bridge that gap and win her affection, Clément leans into the ruse, and to bolster his performance he enlists a trio of legendary cameos. Milton Berle appears as himself to teach him timing, Gene Kelly steps in to coach him on dance, and Bing Crosby offers guidance on song. The sequence of lessons is bright and entertaining, blending humor with showmanship as Clément experiments with delivery, movement, and voice, all in the service of captivating Amanda. The flamboyant aid from these figures also helps the revue outgrow its more modest ambitions, nudging Clément toward a commitment that stretches beyond fame or spectacle. The plot thickens as a theater employee—someone who has raised Clément all his life—falls into a dispute about the theatre’s rent, and Clément’s money becomes a pivotal but morally ambiguous tool to secure the future of the show.
Through it all, a romance blossoms between Clément and Amanda, built on shared vulnerability and a longing to be seen beyond the public spectacle. Clément’s plan to reveal his true identity intensifies the emotional stakes: he decides to come clean, even as Amanda suspects he has been overwhelmed by method acting and may need professional reassurance. The truth finally surfaces when he stages a careful confrontation with Amanda and the revue director, bringing them to his offices to witness the real person behind the persona. Amanda’s initial indignation gives way to forgiveness as the two confront the deception together, and their reconciliation culminates in a tender moment in the building’s elevator, sealing their bond with a quiet, trusting kiss. The film balances satire, romance, and showbiz shimmer, inviting audiences to enjoy a cascade of performances, mistaken identities, and the uneasy but hopeful power of love to transform vanity into something warmer and more enduring.
