Factual error: The sun can't rise out of the Pacific ocean when viewed from America, as seen when Danny is playing the clarinet.
Continuity mistake: In the art studio Richie is working on a painting and it only has a small part finished. In the next shot the painting is completely finished.
Continuity mistake: Several times in the art studio scenes Sonny's paint pallet is replaced with few paintbrushes and vice versa.
Trivia: In his biography, Gene Kelly has admitted that he knew Xanadu was a bad film, but found Olivia Newton-John a joy to work with and she helped him survive it.
Trivia: The "old movie" sequence was shot in front of the rooftop set from "Suddenly" earlier in the movie. You see the exact same buildings, and the same railing, in the background.
Trivia: Olivia Newton-John met her husband, actor and dancer Matt Lattanzi on the set of this film.
Question: The two girls that Danny asks to borrow the bike from, were they two of Kira's sisters?
Chosen answer: No, just people hanging around. Kira was the only one of the sisters sent to earth.
Question: Was the waitress at the end meant to be Kira, or just someone who looked like her?
Chosen answer: It's implied that it could be her, but there's no definitive answer as to whether or not it is. It's deliberately left to the audience's interpretation.
