In the street carnival scene, Genevieve runs across the road to the umbrella shop and gets confetti in her hair and on her clothes, and opens the shop door. When she enters, the confetti has disappeared.
In the final scenes snow falls on the car and on the car front window. As the car pulls off the window has been wiped of snow.
The young couple goes to the theater to see the opera Carmen. The sound track that is used in this scene is not from Carmen, but is just some stock sound track that sounds vaguely operatic.
While the opening shot of the umbrellas passing under the camera is beautiful to look at, the less-than-natural staging of the scene becomes obvious when various pedestrians practically walk into each other, especially one colliding with a policeman, people walk their bikes within inches of each other in perfect parallel lines, and streams of water roll off the camera where normal patterns of rainfall would be.
During the train departure sequence, a very featured lady saying goodbye to her lover clearly looks at the camera as the two protagonists pass by singing.
In the final scene, Genevieve drives off without paying for the tank of gasoline.
In the beginning of the film, set in 1957, there is a picture in Guy's locker at work of Marilyn Monroe wearing an orange boat-neck shirt. The photograph was taken by George Barris in 1962 during her last photo shoot.
