CINEMANIA Leonard Maltin, 1998 Video Review Flashy but empty-headed remake of "Down to Earth," with Olivia Newton-John as muse who pops in to inspire young roller-boogie artist. Designed as a showcase for the singer, but the only thing it showcases is her total lack of screen charisma. Gene Kelly (using his character name from "Cover Girl") tries his best to perk things up; even a brief animated sequence by Don Bluth doesn't help. Newton-John's future husband, Matt Lattanzi, plays Kelly as a young man. Songs include "Magic," by John Farrar and title tune by Electric Light Orchestra.
