Roller disco meets 1940s swing in this kitsch-classic of 1980s Hollywood, featuring Gene Kelly (in his final feature film appearance) as a former big-band sideman who teams up with a down-on-his-luck young artist (Michael Beck) and a beguilingly beautiful Olympian muse (Olivia Newton-John) to turn a decaying theater into a vibrant nightclub. The movie’s song-and-dance numbers include pastiche throwbacks to Kelly’s postwar heyday and glitzy disco-on-wheels set pieces, in which the dizzying mobility of the cinematography becomes integral to the choreography. Said to have inspired the creation of the Golden Raspberry Awards, which celebrate the year’s worst movies, Xanadu has gone down in Hollywood history as a memorably over-the-top genre hybrid, a fantasy-romance-musical with a wildly popular soundtrack performed by Newton-John and Electric Light Orchestra.
