Corrected entry: The ripped pieces of paper from Sonny's drawing land in front of the mural, yet they have all vanished as the muses dance in "I'm Alive."
Corrected entry: During the film Sonny changes from being left-handed to right handed sometimes, while he draws and paints.
Corrected entry: The exterior of Los Angeles' Pan-Pacific Auditorium was used in film for shots of the Xanadu nightclub. The art deco Streamline Moderne building burned down in 1989, though a front spire section was saved and used on the recent Pan-Pacific park community center building which now stands in its place.
Corrected entry: Towards the end after the Xanadu number, the mirrored curtain lifts and an overhead shot shows the eight sisters at the center, then dancing down the pink points of the star illuminated on the stage floor. The dancer at the 6 o'clock position starts down the wrong color point and then corrects herself before she reaches the edge of the stage.
