1960s superstar fashion model Twiggy and Broadway dancing star Tommy Tune headline Ken Russel's lovingly comic homage to the Hollywood musicals of the 1930s in The Boy Friend. When the star of an English stage musical twists her ankle seconds before the curtain goes up, shy, young assistant stage manager Polly (Twiggy) takes her place. Now, the show goes on as Polly sings and dances her way through a kaleidoscope of psychedelic interpretations of choreographer Busby Berkeley's classic musical numbers. While an audience watches, Polly finds love and stardom before the curtain comes down on The Boy Friend.
