Nettles to play Dolly Parton's parents in 'Coat of Many Colors'

Jennifer Nettles, Gerald McRaney and Ricky Schroder have joined the cast of the upcoming TV movie Dolly Parton's Coat of Many Colors, NBC announced.

The small-screen drama is based on the inspiring, true story of country music icon Dolly Parton's remarkable upbringing.

"This once-in-a-lifetime movie special takes place inside the tight-knit Parton family as they struggle to overcome devastating tragedy and discover the healing power of love, faith, and a raggedy patchwork coat that helped make Parton who she is today," a news release said. "The film is set in the Tennessee Great Smokey Mountains in 1955. It is neither a biopic nor musical about Dolly's whole life and performing career, but rather a family-oriented, faith-based story about the incidents in her and her family's life around the time she was nine years old."

Nettles will play Parton's mother, Avie Lee Parton; Schroder will portray her father, Lee Parton; and McRaney will play Grandpa Jake Owens. Newcomer Alyvia Lind will play Dolly Parton as a child.
