The Hallmark Channel is teaming up with the Grand Ole Opry on something that plays to both of their strengths. "A Grand Ole Opry Christmas" is an original holiday movie starring Nikki DeLoach and Kristoffer Polaha, and will premiere during Hallmark Channel’s 16th annual Countdown to Christmas event. The movie will also include "familiar faces from the Opry's star-studded cast" to be announced at a later date. One country performer we know will be involved: Brad Paisley, who has been tapped to write original music for the film as well as perform.
