Xanadu

A young artist is trying to paint his enduring masterpiece (in chalk) on the boardwalk of Venice Beach and before you can say “roller disco!” his Muse appears in the form of Olivia Newton-John to guide him to full artistic satisfaction. Hey, it’s the 80s, they did stuff like this then. Based on the legendary cult film with Newton-John and Gene Kelly, and packed with her chart-topping hits (“Magic,” “I’m Alive,” “Have You Never Been Mellow”), this is inspired lunacy at its most buoyant and hilarious.
