Michael Beck plays artist Sonny Malone
Xanadu on IMDB
'Sonny Malone (Michael Beck) is a talented artist who dreams of fame beyond his job, which is the uncreative task of painting larger versions of album covers for record-store window advertisements. As the film opens, Sonny is broke and on the verge of giving up his dream. Having quit his day job to try to make a living as a freelance artist, but having failed to make any money at it, Sonny returns to his old job at AirFlo Records. After some humorous run-ins with his imperious boss and nemesis, Simpson, he resumes painting record covers.
At work, Sonny is told to paint an album cover for a group called The Nine Sisters. The cover features a beautiful woman passing in front of an art deco auditorium (the Pan-Pacific Auditorium). This same woman collided with him earlier that day, kissed him, then roller-skated away, and Malone becomes obsessed with finding her. He finds her at the same (but now abandoned) auditorium. She identifies herself as Kira (Olivia Newton-John), but she will tell him nothing else about herself. Unbeknownst to Sonny, Kira is one of nine mysterious and beautiful women who literally sprang to life from a local mural in town near the beach.
Sonny befriends a has-been big band orchestra leader-turned-construction mogul named Danny McGuire (Gene Kelly). Danny lost his muse in the 1940s; Sonny has not yet found his muse. Kira encourages the two men to form a partnership and open a nightclub at the old auditorium from the album cover. She falls in love with Sonny, and this presents a problem because she is actually an Olympian Muse (she is Terpsichore, the muse of dance). The other eight women from the beginning of the movie are her sisters and fellow goddesses, the Muses, and the mural is actually a portal of sorts and their point of entry to Earth.'
