Overview
You Light Up My Life is a 1977 American romantic drama film written and directed by Joseph Brooks and starring Didi Conn, Joe Silver, and Michael Zaslow. Laurie (Conn), a talented singer and songwriter, feels obligated to follow her father's borscht belt comedian career. She struggles to get small time acting work in advertising and children's shows with her fellow acting friends in Hollywood and shows marginal talent in standup comedy (mostly set up using her father's connections). Her happenstance meeting with a young director will set the stage for a series of conflicts with her fiancé, father and career decisions.
Plot
Laurie Robinson (Didi Conn) is a young woman who earns a living by performing in commercials and hosting a children's show on public television, but she would rather concentrate on songwriting and singing than doing comedy with her small-time comedian father Si (Joe Silver). One night, Laurie goes to a restaurant where she meets a young film director, Chris Nolan (Michael Zaslow); she drives him back to his apartment and they spend the night together. The next morning, Laurie confesses to Chris that she is engaged and has to be at her wedding rehearsal. He asks if the previous night was just a final fling before marriage, and she says she cannot see him anymore.
Laurie later meets with her fiancé, Ken Rothenberg (Stephen Nathan), and attends a recording session where she records her song, then sings background vocals and directs the musicians during overdubs. From there, she goes to the wedding rehearsal where Si has arranged an elaborate setup with an old friend who owns the Wedding Palace. The next day, Laurie auditions for a film that needs a singing voice for the leading lady. The director, she discovers, is Chris, who is as surprised as she is. Chris asks to see the songs in her portfolio. Laurie's voice and the orchestra's performance of her song "You Light Up My Life" impresses everyone, and Chris asks her if she would be interested in auditioning for the lead in his movie.
Later, Chris sings "You Light Up My Life" for Laurie at his piano, giving it a more subdued treatment, then takes her for a walk along the beach. Laurie visits her best friend Annie (Melanie Mayron) to confess that she loves Chris, and adds that she may have the lead in his film.
