Xanadu [VHS]
A wimpy remake of an already anemic movie (the 1947 Rita Hayworth vehicleDown 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.--Tom Keogh
