Dolly Parton’s ‘Mountain Magic’ Christmas just got bigger.

Willie Nelson, Jimmy Fallon, Billy Ray Cyrus, Jimmie Allen, Zach Williams and Miley Cyrus have all signed on as guest stars.

In addition to Parton in the lead role, the film also stars Tom Everett Scott, Ana Gasteyer and Angel Parker.

According to a press release, the film is “a modern-day movie musical about the making of a network TV special.”

“Dolly finds herself taking a private journey into her past, guided by the mysterious appearances of her personal ‘Three Wise Mountain Men.’ When it’s time for her big special to air, a renewed and inspired DOLLY goes rogue and shows the world that the real magic of Christmas lies in the hearts of the children we all once were, the realization that Christmas is about the people we share it with, and how her faith remains the common thread between Christmases past, present, and future,” according to the show description.

Dolly was recently spotted filming scenes with Willie Nelson at Dollywood.
