The Music, The Film, A Place Where Dreams Come True. 　　The Greek muses incarnate themselves on Earth to inspire men to achieve. One of them, incarnated as a girl named Kira, encounters an artist named Sonny Malone. With the help of Danny McGuire, a man Kira had inspired forty years earlier, Sonny builds a huge disco roller rink. 　　A wimpy remake of an already anemic movie (the 1947 Rita Hayworth vehicle Down to Earth), this glitzy musical from 1980 improbably stars Olivia Newton-John as a heavenly muse sent here to help open a roller-derby disco. Gene Kelly is mixed up in this well-meaning but goofy effort to fuse nostalgia with late-'70s glitter-ball trendiness, and he looks just plain silly. Directed by Robert Greenwald, the film doesn't even work as decent kitsch.
