You Light Up My Life is a 1977 American romantic drama film written, produced, scored, and directed by Joseph Brooks.

Her happenstance meeting with a young director will set the stage for a series of conflicts with her fiancé, father and career decisions.

[5] 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).

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.

Later that night, when Laurie and Si perform at the Family Komedy Hour, her routine falls flat, tears flood her eyes and she walks off.

In the dressing room, Laurie tells Si she hates the act because she is not funny, all she wants to do is sing and that Columbia Records is interested in her.
