Darin, Kevin Spacey grows from a frail, disease-plagued kid born Walden Robert Cassotto in the Bronx into a chart-topping singer whose fame some say surpasses even Frank Sinatra. Rather than a straight biography, the film unfolds as a tapestry blending fantasy sequences with largely fictionalized moments from his life, and throughout it, the adult Darin meets his younger self in a recurring, almost surreal dialogue between past and present. He forms a band, hustles for gigs, and clings to a dream of stardom that refuses to be denied.
At Atlantic Records, the young performer rides a wave of teen idol success with the bubbly single Splish Splash, a name that helps him win fans across a broad age range. He refuses to be pigeonholed into one sound, steering his career toward big-band arrangements and producing major hits like Mack the Knife, a mark of his evolving versatility and theatrical charisma. To expand his appeal to teens and young adults alike, Darin is cast in Come September opposite Sandra Dee, Kate Bosworth as the 18-year-old actress who captures his heart. He falls deeply for her, serenading her with songs like Beyond the Sea and Dream Lover, and the couple eventually elopes, much to her mother’s dismay. The moment seems to fulfill a family dream when Darin is finally booked to perform at the famed Copacabana in Manhattan.
As touring and stardom pull him away from home, Dee’s life on the road grows rocky; she turns to hard drinking, and the couple’s fierce passion gives way to frequent quarrels. Their relationship strains until they briefly part and later reconcile, with Dee giving birth to their son, Dodd. Amid the personal highs, Darin earns a serious professional accolade when he’s nominated for the Academy Award for Best Supporting Actor for portraying a shell-shocked soldier in Captain Newman, M.D., a role that adds a new layer of gravitas to his public image, even as private tensions simmer beneath the surface.
In the late 1960s, Darin becomes involved in the Robert F. Kennedy presidential campaign and considers politics as a new frontier. His sister Nina, wary of what the press would uncover about his past if he pursued public life, delivers a shocking revelation: his beloved mother was actually his grandmother, and he is Nina’s illegitimate son. This discovery shatters him, and he retreats into seclusion, living in a trailer along the Big Sur coast. The world around him has shifted, and the old musical currents no longer flow as they once did; folk tunes and protest songs begin to infiltrate his repertoire, but the audience that adored him drifts away, leaving him feeling out of step with changing tastes.
Still, he presses on, staging a daring comeback—a full-scale Las Vegas show at the Flamingo Hotel, complete with a gospel choir and a renewed sense of purpose. The performance is a triumph, a testament to his resilience and stubborn dedication to artistry despite the odds. Yet triumph is fleeting, and his health begins to fail after surgery to repair a mechanical heart valve leaves him with blood poisoning. He dies at the age of 37, but not before one final moment of connection: he encounters his younger self once more, and the two share a last duet on the aging, enduring sentiment of perseverance, singing “As Long as I’m Singing” as the curtain falls.
The film’s emotional throughline remains: a man who refused to surrender to the limits others set for him, who chased a dream with the stubborn warmth of a balladeer and the showmanship of a star. It’s a portrait of ambition, love, family secrets, and the price of fame, told through a blend of memory and fantasy that keeps the gaze fixed on the man behind the myth, supported by a cast that anchors the film in human texture: John Goodman offers a grounded counterpoint to Darin’s larger-than-life persona, while Kate Bosworth embodies the bright allure—and the vulnerability—of the actress who shared his life. The result is a sprawling, intimate, and always cinematic meditation on a life that burned bright and burned out in the glare of the spotlight.
