One of the Big 4 broadcast networks is pumped up today about a movie that aired on the network last night. NBC announced that “Coat of Many Colors,” based on a true story from the childhood of legendary country singer Dolly Parton, is the most-watched movie on the broadcast networks in three and a half years, excluding live musicals.

The movie, which stars Alyvia Alyn Lind, Jennifer Nettles and Ricky Schroder, delivered 12.842 million total viewers, NBC reports, adding that the number is the highest since “Jesse Stone: Benefit of Doubt” delivered 12.932 million on May 20, 2012.

That gap covers a span of 100 movies — theatrical, made-for-TV and direct-to-video films and miniseries aired in prime time on the Big 4, NBC notes.

“Excluding sports and live musicals, [‘Coat of Many Colors’] delivered NBC’s top total-viewer result in the time period in six years, since the ‘ER’ finale on April 2, 2009 (16.4 million),” NBC reports, adding that the movie is “NBC’s most-watched scripted telecast since the ‘SNL 40’ special Feb. 15 (23.1 million).”

Here’s the official teaser:
