In a very rare move that may or may not have something to do with the NFL on NBC, Fox will broadcast an original TV movie. It was among the first networks to abandon the once-popular genre. And it’s interesting to note that the original made-for-television romance “Change of Plans” (7 p.m., Fox) has a strong “American Idol” connection.

It marks the acting debut of season-eight finalist Brooke White. Fans of the series may remember her as the striking blonde singer/songwriter who surprised Simon Cowell when she declared that she had never seen an R-rated movie. For the record, “Change of Plans” is strictly PG.

White plays Sally, a musician with a fighter-pilot husband (Joe Flanigan, “Stargate: Atlantis”) whose life is upended when her best friend dies and leaves Sally as the legal guardian of her four children. What would television do without the plot line of instant parenthood? Look for Phylicia Rashad of “The Cosby Show” as a social worker as well as cameos from “Idol” judge Randy Jackson and NASCAR driver Jeff Burton.
