“A Grand Biltmore Christmas” will air during the 2026 Christmas season. The initial movie starred Bethany Joy Lenz and Kristoffer Polaha, both of whom will pop up in the new Biltmore movie. MacDowell will play the character of Aunt Maysilee, who is described as a “prim, somewhat matronly yet spirited” woman. As Southern Living shares, the two first meet on Christmas Eve in 1895 on the opening night at Biltmore House. She is joined by her romantic partner, James, as well as her Aunt Maysilee.
