Back in 1977, Debby Boone's "You Light Up My Life" became the biggest hit single of the entire decade. Many forget that the song emanated from a much less successful movie of the same title.
Laurie Robinson (Didi Conn) grows up in a showbiz family and her comedian father Si (Joe Silver) expects her to follow in his particular footsteps. Laurie does this but she feels unfulfilled.
Instead of comedy, Laurie would like to concentrate on singing and songwriting. Laurie attempts to pursue her career goals while she also deals with romantic conflicts.
Stuff What I Just Learned Today: Boone's version of the title song appears nowhere in the film. Instead, Conn lip-synchs a rendition sung by Kasey Cisyk.
While Boone's sold roughly 87 bajillion singles, Cisyk's peaked at #80. Well, at least that one snared an Oscar.
Which became the only recognition the Academy gave to the movie. This became the case for good reason, as the cinematic Light offers few pleasures.
And by “few”, I mean “pretty much none”. If forced to choose a positive, I’d spotlight Conn, as she offers a more than competent performance.
That said, Conn seems miscast. While cute, she doesn’t appear conventionally attractive and she brings a high-pitched, squeaky voice that don’t fit the role.
Those characteristics worked in supporting roles like the “beauty school dropout” Frenchy in 1978’s hit Grease. As a romantic lead, Conn just doesn’t fit.
That said, Conn brings some heart and spirit to a poorly defined part. Laurie offers a highly reactive character with little real personality but Conn manages to add a bit of spirit.
But not enough to make Laurie interesting, and it becomes absolutely impossible to imagine cartoon-voiced Conn as the smooth and rich singer who croons throughout the film. The mismatch between Conn’s chirping dialogue and Cisyk’s crooning provides unintentional hilarity.
In many ways, Light feels like a riff on The Jazz Singer. We get another father who tries to force his offspring into the family business, whereas the child wants to go down a path the parent doesn’t like.
If Light spent most of its time with this theme, it would remain derivative but it could work. Instead, most of the movie follows Laurie’s uninteresting love life.
These scenes fail miserably. Though basically a female liberation tale where Laurie learns to stand on her own, her passive nature means that Light sputters.
It doesn’t help that various attitudes have aged awfully poorly. For instance, we find a legitimately bonkers scene in which Cris Nolan (Michael Zaslow) forces himself on Laurie and she just goes along with it.
Granted, we can accept that the 1970s was a loosey-goosey time for sexual conquests. Nonetheless, this still seems contrived and phony and fairly offensive nearly 50 years later.
Really, the entire romance triangle subplot seems extraneous. A bit of Laurie’s love life might’ve worked, but Light throws in far too much of this tedious material.
Throw in an unintentionally hilarious scene in which Laurie goes through an over-the-top mental breakdown and You Light Up My Life becomes a ridiculous and poor film. Beyond the modest charms of Didi Conn, nothing about it works – and I hate that awful title song, too!
