XANADU - ULTRA HD - Olivia Newton-John stars in this fantastical musical odyssey as Terpsichore, the Greek muse of dance, who visits Earth as a human to inspire a young artist (Michael Beck). Aided by an ex-Big Band musician (Gene Kelly), they open a glitzy disco roller rink, but what happens when muse and mortal fall in love? Colorful updating of 1947's "Down to Earth" features songs by Newton-John and ELO, including "Suddenly," "Magic," and "All Over the World." Two-disc set. RUNTIME: 96 min.
