Since it began last July, the Colony Theater’s Music at the Movies series has covered rock ‘n’ roll (“The Last Waltz,” “High Fidelity”), old-timey bluegrass (“O Brother, Where Art Thou”) and the blues (“The Blues Brothers”), but this Thurday night, their spotlight shines on disco with a screening of Robert Greenwald’s “Xanadu” (1980).

A flop during its original theatrical run, the movie has developed a cult following, and inspired a 2007 Broadway musical. Olivia Newton-John stars as the muse of an artist played by Michael Beck, with the backdrop of a roller-skating nightclub named Xanadu. It’s not all disco though, as the soundtrack features ELO, the Tubes and Gene Kelly, in this his final film. It starts at 7:30, and admission is $5.50.
